SKF in mining: which bearings are used in crushers, mills, screens and conveyor belts

SKF deep groove ball bearings are a common choice in mining equipment when loads are moderate and speeds are high. They are used in electric motors, fans and auxiliary pumps within processing plants. Their simple design allows quick assembly and quiet operation under controlled conditions. In mining, they usually appear in peripheral components rather than in the main shafts of crushing or grinding.

To identify an SKF deep groove ball bearing on a machine, look for the code engraved on the side face, such as 6010, 6008 or 6026. The code indicates the series and the bore size. If the part is very worn, measure the inner diameter, outer diameter and width with a caliper. With that data we can confirm the exact reference your equipment needs.

When ordering a deep groove ball bearing for mining, send the complete code, the engraved brand and a photo of the part. Avoid confusing similar series: a 6008 and a 6208 are not interchangeable even if they look alike. If the bearing works in a dusty or humid environment, ask about sealed variants such as 2RS, which have rubber protection on both sides. We sell genuine SKF bearings and will quote you promptly.

SKF cylindrical roller bearings withstand high radial loads and allow axial displacement on the shaft. In mining they are found in gearboxes, high-power motors and some crusher transmission systems. Their load capacity is greater than that of a deep groove ball bearing of the same size, making them suitable for heavy shafts. The separable design facilitates assembly and disassembly in tight spaces.

Our catalog includes, for example, the N3055 and references such as RNU 305 or RNU 306, which do not have an inner ring: the rollers run directly on the shaft. To order them, note the complete code and check whether the bearing is single-row or double-row. If the number is not legible, measure the bore diameter, outer diameter and total width.

When quoting cylindrical roller bearings for mining, indicate if they work with combined axial loads. In that case, a series with flanges on both rings may be preferable. Avoid forcing assembly with direct blows on the rollers: use a suitable sleeve or press. We distribute SKF bearings for mining applications and help you identify the correct reference with a photo or measurements.

SKF spherical roller bearings are among the most used in mining for their ability to absorb misalignments and combined loads. They appear in the main shafts of ball mills, jaw crushers and conveyor belt drums. Their design with two rows of rollers on a spherical raceway allows the shaft to tilt without damaging the bearing. This is key in equipment subjected to bending and foundation settlements.

References such as 22325, 22361 and 23666 are examples of this category in mining applications. The code indicates the series and bore diameter; for example, the 223 series is very common in mills. When ordering a spherical roller bearing, check whether the bore is cylindrical or tapered. The suffix K indicates a tapered bore, which is mounted on an adapter sleeve or directly on a tapered shaft.

To quote an SKF spherical roller bearing, send the complete code and the type of equipment where it works. If the bearing is severely deteriorated, measure the bore diameter, outer diameter and width. Avoid replacing a spherical roller bearing with a deep groove ball bearing: it will not withstand the loads or misalignments. We sell SKF bearings for mining and will indicate the exact alternative for your machine.

SKF angular contact bearings withstand combined radial and axial loads in one direction. In mining they are used in centrifugal pumps, gearboxes and drilling equipment spindles. Their design with a contact angle allows absorbing significant axial thrusts, such as those generated by a slurry pump. They are mounted in pairs or special configurations to withstand loads in both directions.

Codes such as 7417, 7453 and 7829 appear in our catalog as SKF angular contact bearings. To identify them on a machine, look for the engraved number and observe if the bearing has an offset raceway. If the code is not legible, measure the inner diameter, outer diameter and width, and note the direction of the axial load. It is important to know if the bearing works alone or together with another.

When ordering SKF angular contact bearings for mining, indicate the mounting arrangement: tandem, back-to-back or face-to-face. This defines the axial load capacity of the assembly. Avoid mounting an angular contact bearing backwards: the contact angle must match the load direction. We distribute genuine SKF bearings and quote you with the code or measurements of your equipment.

SKF Y-bearings, also called inserts, are units with cast iron or sheet metal housings that simplify mounting on long shafts. In mining they are used in conveyor belt pulleys, screen rollers and screw conveyors. Their design with an eccentric bore or set screws allows fixing them to the shaft without complex adjustments. They are ideal for equipment requiring quick bearing changes.

Typical examples are UC 216, UC 315 and UC 212, which are mounted in pillow block or flange housings. To order a Y-bearing, note the complete code of the insert and the housing if you need it. If the number is not legible, measure the shaft diameter and the distance between the housing bolt holes. It is also useful to know if the housing is cast iron, sheet metal or thermoplastic.

When quoting SKF Y-bearings for mining, indicate if the environment has dust, water or intense vibration. In those cases, it is better to choose inserts with reinforced seals or more robust cast iron housings. Avoid reusing a damaged housing: it can misalign the new bearing and reduce its service life. We sell SKF Y-bearings and advise you on the correct configuration for your conveyor or screen.

SKF tapered roller bearings withstand high radial and axial loads in one direction. In mining they appear in cone crushers, mill gearboxes and mining cart wheels. Their design with tapered rollers and raceways allows the cone and cup to be disassembled separately, which facilitates mounting. They are used in opposing pairs to withstand axial loads in both directions.

Tapered roller bearings are identified by a code that indicates the series and bore size. When ordering them, note the complete code of the cone and cup, which are sometimes sold separately. If not legible, measure the inner diameter, outer diameter and total width.

To quote SKF tapered roller bearings for mining, indicate if they are mounted in pairs and with what preload. Incorrect adjustment can generate excessive temperature or axial play. Avoid mixing cones and cups from different brands: tolerances do not match. We distribute SKF bearings and help you define the exact reference with a photo or measurements of your equipment.

SKF rod ends and spherical plain bearings are connecting components that allow angular and oscillating movements. In mining they are used in hydraulic cylinders, loader arms and suspension systems of mobile equipment. Unlike bearings, they do not rotate continuously but work with slow movements and high loads. Their maintenance usually requires periodic lubrication to prevent premature wear.

To identify an SKF rod end, look for the code engraved on the body or on the label if it is new. If not legible, measure the bore diameter, width and thread type if it has one. It is also important to know if the rod end requires lubrication or is self-lubricating. In mining, sealed rod ends are preferable to prevent the ingress of dust and water.

When ordering SKF rod ends and spherical plain bearings for mining, send the complete code and a photo of the part. Indicate if it works in a hydraulic cylinder, an articulated arm or a suspension. We sell genuine SKF rod ends and spherical plain bearings and quote you promptly with your equipment data.
