SKF Bushings and sleeves

SKF PTB series friction bushings sit between a shaft and a housing to cut friction and wear. They handle radial loads in rotating or oscillating motion and can run self-lubricated or with lubrication. Industrial and automotive equipment that needs a compact, low-maintenance solution is where they fit best. MR supplies this line alongside its power transmission and support components.

SKF PCM E series plain bearings are thin-walled bushings with a sliding coating, built for radial loads in oscillating or limited-rotation movements. They suit joints, pivots and guides where friction must stay low and maintenance kept to a minimum. MR Industrial Accessories LLC supplies this line within its range of power transmission and motion components.

SKF PCM M plain bearings are thin-walled, self-lubricating bushings. A steel backing supports a sintered bronze layer, topped with a PTFE and lead mixture. They handle radial loads in oscillating, rotating or sliding movements where a continuous lubricant supply is not practical. Their slim profile fits tight spaces and lets them replace solid bushings that have lower load capacity.

When a bearing with a tapered bore needs to sit on a plain shaft that has no machined shoulder, an adapter sleeve does the job. It slides along the shaft to the working position and is locked in place with a nut, so the bearing can be set exactly where it is needed. SKF H series sleeves cover this mounting method for 22 series spherical roller bearings and self-aligning ball bearings.

The SKF HE series adapter sleeve allows a bearing with a tapered bore to be fitted onto a cylindrical shaft. The assembly includes an externally threaded sleeve plus a lock nut and lock washer; tightening the nut produces the interference that holds the bearing in place. Typical uses include gearboxes, pumps, fans and conveyors, where a secure connection that can still be removed is needed.

The SKF HA series adapter sleeve is a mounting assembly that secures a tapered-bore bearing onto a cylindrical shaft. It includes a split sleeve, a lock nut, and a lock washer. This design allows precise positioning and straightforward removal, making it a practical choice for power transmission equipment, gearboxes, and other industrial machinery where the bearing's axial location must be set or the assembly needs to be taken apart without damaging the shaft.

The SKF KM series lock nut is used to secure bearings on shafts, allowing controlled adjustment during mounting and maintenance. It works together with a lock washer to hold the bearing in position. This nut is common in power transmission assemblies where axial movement must be limited.

When a bearing with a tapered bore needs to be held firmly on a shaft, the SKF KMT series lock nut provides precise adjustment and dependable retention. Its design simplifies both installation and removal, which helps keep rotating equipment serviceable.

The SKF HM series lock nut is a precision fastening component designed to hold bearings and other shaft-mounted parts in place. It features a metric thread and slots for a hook spanner, allowing secure and adjustable tightening. This makes it a practical choice for industrial settings where dependable and straightforward installation is required.

The SKF AOH withdrawal sleeve threads onto the shaft to help pull off bearings that have a tapered bore. It is designed for situations where the bearing is press-fitted and standard pullers cannot be used. MR supplies this series in sizes that match different shaft diameters.

The SKF AH series withdrawal sleeve is designed to remove bearings with tapered bores cleanly, without harming the shaft or the bearing. It is a common choice for industrial maintenance tasks where safe and efficient disassembly matters.

When a bearing with a tapered bore has to come off the shaft without scoring the seat or the inner ring, the SKF AOH G series withdrawal sleeve is the component that makes it possible. It mounts on the shaft and, with a precision lock nut, provides a controlled way to extract the bearing. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams across the United States and Latin America.

When a bearing must be seated with an interference fit that a press or hammer cannot handle, the SKF HMV …E hydraulic nut provides a controlled alternative. It screws onto the shaft or adapter sleeve and uses oil pressure to expand the fitted component, so the seat surfaces stay undamaged. This nut belongs to the mounting tool family that MR Industrial Accessories LLC supplies to maintenance teams across the United States and several Latin American countries.

The SKF HMV /233983 designation points to a spare seal kit for hydraulic nuts. The image displays O-rings, but the item itself is the sealing component, not the complete hydraulic nut.

For press-fit work on shafts and in housings, the SKF HMVC …E series hydraulic nut gives maintenance crews a controlled way to seat or release bearings and sleeves. Hydraulic pressure produces an even axial push, which helps protect the components being fitted and simplifies the job where space is tight. Workshops and plant maintenance departments use it when the work has to be done quickly and without risking the parts.

The SKF MB series lock washer is a key component in bearing mounting systems. It works with a slotted lock nut to hold bearings and other parts firmly on threaded shafts. An inner tab engages a groove on the shaft, while outer tabs are bent into notches on the nut, creating a mechanical lock that resists vibration and rotation. MR Industrial Accessories supplies this series as part of its range of bearing accessories.

A SKF lock washer from the W series sits between the bearing lock nut and the bearing, holding the nut at the position you set. Two tabs do the work: the inner one locates in the shaft groove, the outer one folds over a nut face. Assemblies on shafts where a nut working loose would be a problem are where these washers belong.

SKF MS lock clips are locking elements for lock nuts, secured with a screw. Each clip is identified by its full designation and by the lock nut it fits.

The SKF SNW series inch adapter sleeve secures bearings with a tapered bore onto cylindrical shafts. It provides a reliable, adjustable fit in power transmission, pump and general industrial equipment. MR Industrial Accessories LLC supplies this series to customers across the United States and Latin America.

For tapered bore bearings, the SKF OH..H hydraulic sleeve provides a controlled way to seat and release the bearing using oil pressure. This helps maintenance teams work with the required interference fit while limiting stress on the shaft and bearing.

The SKF OH HTL hydraulic sleeve is a tool for installing and removing bearings with a tapered bore. It uses oil pressure to reduce the force needed and to protect both the bearing and the shaft. Maintenance workshops that value precision and care will find it a practical choice.
