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

In mining, Timken tapered rollers appear in jaw, cone and gyratory crushers, where they withstand combined loads and impacts. Their design allows the assembly to be disassembled relatively easily, which is key in equipment working with abrasive material. To get a quote, it is best to send the part number engraved on the race or a photo of the part with the inner diameter, outer diameter and width measurements.

In ball and rod mills, these bearings are used on the trunnions and in the drive systems, where the load is constant and heavy. A common mistake is replacing a tapered roller with a ball bearing without checking the load capacity: the tapered one is designed to absorb combined axial and radial thrusts. If the original bearing has suffixes, they must be respected when ordering the spare part.

When ordering a tapered roller for mining, in addition to the part number it is advisable to indicate the equipment and the mounting position. In crushers, the bearings on the flywheel side are often different from those on the crushing chamber side. If you do not have the part number, measure the inner diameter, outer diameter and total width with a caliper, and send a photo of the race where the brand is visible. We will quote you the exact spare part or the equivalent alternative according to the application.

Timken spherical rollers are used in large mills, rotary kilns and dryers, where the shafts can misalign due to base settling or expansion. Their double-row roller design with a spherical race in the outer ring absorbs misalignment. Part numbers such as 21310EJ, 21311EJ and 23030EJ are examples of spherical rollers.

In these machines, the bearing is usually mounted on an adapter or withdrawal sleeve, which makes assembly and disassembly easier. It is important to check the fit of the sleeve and the lock nut, because poor tightening generates vibration and reduces service life. If the original bearing has a tapered bore and comes with a sleeve, do not replace it with a cylindrical-bore one without consulting.

To get a quote for a spherical roller for mining, send the full part number, including the suffix, and if possible a photo of the equipment's identification plate. The inner and outer diameter and width measurements are also useful. We stock Timken and will indicate the correct option for your mill, kiln or dryer, with the corresponding mounting accessories.

Timken deep groove ball bearings are used in centrifugal pumps, fans, compressors and electric motors within the mining plant. They are versatile and withstand moderate radial and axial loads. Part numbers such as 6010, 6011 and 6210 are examples of deep groove ball bearings.

In mining, these bearings are often ordered with seals or metal shields. If the bearing works in a highly contaminated environment, it is advisable to choose a sealed version and a good grease.

When ordering a deep groove ball bearing for mining, indicate the part number and whether it has seals or shields. If you do not have the part number, measure the inner diameter, outer diameter and width, and send a photo of the part. We will quote you the exact Timken bearing or the equivalent alternative.

Timken angular contact bearings are used in high-pressure pumps, gearboxes and machine tool heads within the mining operation. They withstand combined loads, with axial thrust.

In mining applications, these bearings are often in conveyor belt gearboxes or in slurry pumps, where axial load is important. It is key to respect the equipment's original mounting arrangement.

To get a quote for an angular contact bearing for mining, send the full part number and, if possible, a photo of the assembly showing how it is mounted. Indicating the equipment and position is also useful. We stock Timken and help you choose the correct bearing for your gearbox or pump.

Timken housings are used in conveyor belts, bucket elevators and feeders, where they simplify assembly and maintenance. They simplify mounting the bearing onto the structure. Part numbers such as LSM50, MSM50 and LSM70 are examples of housings from the catalog.

In mining, these housings go at the ends of conveyor pulleys, on carrying rollers and in tensioning systems. It is important to check the shaft center height and the distance between mounting holes, because there are variants according to the standard.

When ordering a housing for mining, indicate the housing or internal bearing part number, and if possible a photo of the identification plate. If you do not have the part number, measure the shaft diameter, the center height and the distance between holes. We will quote you the complete Timken housing or only the replacement bearing, as you need.

Timken covers and accessories for housings protect the bearing from dust, moisture and suspended material, very common in mining. They include blind covers, sealed covers, lock rings and lubrication systems. These components are ordered by the housing part number or by the internal bearing measurements, and are key to extending service life under severe conditions.

In crushers and screens, the covers help prevent mineral dust from entering the bearing. A frequent mistake is reusing damaged covers or ones with worn seals. It is advisable to maintain the original cover design.

To get a quote for covers and accessories for mining, send the housing part number or a photo of the cover with its measurements. If you do not have the part number, indicate the shaft diameter and the cover outer diameter. We stock Timken and will quote you the exact cover or accessory for your housing.

Timken adapter and withdrawal sleeves are used to mount bearings with a tapered bore on cylindrical shafts, very common in mills and fans. The adapter sleeve is tightened with a nut. The withdrawal sleeve is used to facilitate bearing removal.

It is important to choose the correct sleeve according to the shaft diameter and the bearing bore.

To get a quote for a sleeve for mining, indicate the bearing part number or the shaft diameter and the bearing bore. If you have the old sleeve, send a photo with the inner and outer diameter measurements. We will quote you the exact Timken sleeve or the equivalent alternative.
