Dodge in mining: what is used in crushers, mills, screens and conveyor belts, and how to order it

In mining, Dodge Y-bearings and inserts are used at points where mounting and dismounting must be quick, such as on conveyor belts, screens and feeders. They are single-row ball bearings with a spherical outer ring and an insert that is fixed to the shaft by means of set screws or eccentric locking. This construction allows small misalignments to be absorbed and simplifies field replacement. References such as INS-ER-DL-102, INS-ER-DL-103 and INS-ER-DL-104 are examples of Dodge inserts that can be quoted.

To order a Dodge insert, it is advisable to record the shaft diameter, the locking method (set screws or eccentric) and the seal type. The internal clearance must also be verified: in applications with variable loads or temperatures, a clearance greater than normal may be required. If the part has a code engraved on it, that data can be used for the quote.

A common mistake is to confuse the insert with the complete housing or to order only by the housing size. The insert is identified by the shaft diameter and the housing series that houses it. Before quoting, it is advisable to send a photo of the part and the main dimensions. At MR we sell Dodge inserts and help identify the correct replacement for each mining equipment.

Dodge Y-housings with insert bearing combine the insert with a cast iron or sheet steel housing, and are mounted on conveyor structures, drums and conveying equipment. The housing can be pillow block, flange or take-up, depending on the position and the belt adjustment system. In mining, robust housings are chosen, with good anchoring and protection against contaminants.

When ordering a complete housing, the shaft diameter, the housing type (pillow block, flange, take-up) and the housing material must be indicated. It is also important to know whether the insert comes with a single or double seal, and whether the housing has a grease fitting. The reference engraved on the housing or on the insert makes the search easier.

A frequent mistake is to reuse the old insert in a new housing without verifying the fit and the condition of the housing. The insert must fit firmly and allow self-alignment. If the housing is damaged or deformed, it is advisable to replace the complete assembly. At MR we distribute Dodge Y-housings with insert and help you define the right configuration for your mining application.

In addition to Y-housings, mining uses pillow block and take-up housings for larger shaft diameters and heavier loads, such as in mills and crushers. They are fixed to the structure by means of bolts and allow simpler mounting and dismounting on large equipment. In mining, the choice of housing depends on the shaft diameter, the radial and axial load, and the alignment conditions.

To quote a Dodge housing, it is advisable to record the shaft diameter, the distance between centers of the anchor bolts and the height from the shaft center to the base. It must also be indicated whether the housing is pillow block, flange or take-up, and whether it needs a cap or gland. If the original equipment has a split housing, it can be replaced by an equivalent one by verifying the mounting dimensions. The series codes can be consulted with the MR technical team.

A common mistake is to order the housing only by the bearing number, without verifying the housing dimensions. The housing must match the bearing seat and the fixing holes. At MR we sell Dodge housings for mining and guide you in the selection.

Dodge pulleys are used in conveyor belts, elevators and belt drive systems in mining. They can be take-up, drive or tail pulleys, with tapered bushings for safe mounting. In mining applications, pulleys are chosen with good balance, abrasion resistance and capacity to withstand impact loads.

To order a Dodge pulley, the outside diameter, the rim width, the bushing type and the shaft diameter must be indicated. It is also important to know the belt type (V-belt, synchronous or flat) and the number of grooves. If the pulley has a tapered bushing, it is advisable to verify the bushing code and the recommended tightening torque.

A common mistake is to measure only the outside diameter and forget the rim width or the bushing type. The pulley must be compatible with the shaft and with the existing belt. If there is wear in the grooves, it is advisable to replace the complete pulley and check the alignment. At MR we distribute Dodge pulleys for mining and help you identify the correct reference.

Dodge reducers are used in drives for conveyor belts, mills, crushers and other mining equipment where speed must be reduced and torque increased. In mining, robust reducers are selected, with good heat dissipation and suitable for continuous service. References Maxum XTR 60, Maxum XTR 80 and Maxum XTR 50 are examples of Dodge reducers that can be quoted.

To quote a Dodge reducer, it is advisable to indicate the motor power, the input speed and the required output speed, or the reduction ratio. The mounting type (feet, flange, hollow shaft) and the shaft position must also be defined. In mining applications, the service factor and shock loads must be considered.

A common mistake is to order a reducer only by the reduction ratio, without verifying the power and the allowable torque. The reducer must withstand the actual loads of the equipment and have an adequate safety margin. The lubrication and sealing system must also be checked to prevent contamination. At MR we sell Dodge reducers for mining and advise you in the selection.

Dodge tapered bushings are used to fix pulleys, sprockets and other components to shafts in mining equipment. The tapered bushing system allows quick mounting and dismounting, with uniform tightening and without the need for long keyways. In mining, tapered bushings are chosen for their capacity to transmit torque and their resistance to vibration. They are identified by the shaft diameter and the bushing type.

To order a Dodge tapered bushing, the shaft diameter, the bushing type and the component to be fixed (pulley, sprocket, etc.) must be indicated. It is also advisable to verify the tightening torque of the screws and the condition of the tapered surfaces. If the bushing is damaged or has slip marks, it must be replaced together with the component. The bushing codes can be consulted with the MR technical team.

A common mistake is to reuse a tapered bushing that has already suffered slipping or excessive tightening. The bushing must fit perfectly in the hub and on the shaft, without play. In applications with alternating loads, it is advisable to periodically check the screw torque. At MR we distribute Dodge tapered bushings and components for mining and help you select the correct one.

Dodge sprockets and chain wheels are used in chain drives in mining equipment, such as feeders, conveyors and lifting systems. They are defined by the pitch, the number of teeth and the bushing type, which can be tapered to facilitate replacement. In mining, sprockets with surface treatment are chosen to resist wear and abrasion. V-belts complement pulley drives in fans, pumps and compressors.

To quote a Dodge sprocket or chain wheel, the chain pitch, the number of teeth, the shaft diameter and the bushing type must be indicated. For V-belts, the profile (A, B, C, etc.) and the length must be recorded. If the part has a code engraved on it, it is advisable to send it together with a photo. In mining applications, it is important to verify the alignment between sprockets and the chain or belt tension.

A common mistake is to order a sprocket only by the number of teeth, without verifying the pitch and the chain type. The sprocket must be compatible with the existing chain and with the shaft bushing. In belts, an incorrect length can cause slipping or overload. At MR we sell Dodge sprockets, chain wheels and belts for mining and guide you in the selection.
