SKF Bushings and sleeves

SKF PTB series friction bushings are cylindrical components mounted between a shaft and a housing to reduce friction and wear. They work as self-lubricating or lubricated bushings, supporting radial loads in rotating or oscillating movements. They are used in industrial and automotive machinery and equipment where a compact, low-maintenance solution is required. MR Accesorios Industriales sells this line as part of its range of power transmission and support components.

SKF plain bearings of the PCM E series are thin-walled bushings with a sliding coating, designed to withstand radial loads in oscillating or limited-rotation movements. They are used in joints, pivots and guides where low friction and minimal maintenance are required. MR Accesorios Industriales sells this line as part of its range of components for power transmission and motion.

SKF PCM M series plain bearings are thin-walled self-lubricating bushings that combine a steel backing with a sintered bronze layer and a PTFE and lead mixture. They are used to support radial loads in oscillating, rotating or sliding movements, where continuous lubricant supply is not possible or not advisable. Their compact design allows them to be mounted in confined spaces and to replace solid bushings with lower load capacity.

An adapter sleeve is a tapered element that allows a bearing with a tapered bore — such as 22 series spherical roller bearings or self-aligning ball bearings — to be mounted on a plain shaft, without the shaft needing a machined shoulder or a keyway.

The SKF HE series adapter sleeve is a key component for mounting bearings with a tapered bore on cylindrical shafts. It consists of a sleeve with an external thread and a lock nut with a lock washer that, when tightened, generates the necessary interference to secure the bearing. It is used in rotating equipment where a firm, removable connection is required, such as gearboxes, pumps, fans and conveyors.

The SKF adapter sleeve series HA is a mounting component that allows bearings with a tapered bore to be fixed onto cylindrical shafts. It consists of a split sleeve, a lock nut and a lock washer, and is used to position and secure the bearing in applications where a precise fit and easy disassembly are required. It is a common solution in power transmission equipment, gearboxes and industrial machinery.

The SKF KM series lock nut is an essential component for mounting and securing bearings on shafts. Its design allows precise and secure adjustment, facilitating the installation and maintenance of transmission systems. Manufactured with high-quality materials, it guarantees durability and resistance in demanding industrial applications. It is compatible with a wide range of bearings and is used together with lock washers to secure the bearing position on the shaft.

The SKF KMT series lock nut is a precision component used to secure bearings with a tapered bore to shafts, with safe retention and exact adjustment. Its design allows simple mounting and dismounting, making maintenance of rotating equipment easier. It is ideal for applications requiring reliable and repeatable retention.

The SKF HM series lock nut is a precision component used to secure bearings and other elements onto shafts. Its design with metric thread and hook spanner slots allows firm and adjustable mounting. It is ideal for applications requiring reliable fastening that is easy to install in industrial environments.

The SKF AOH series withdrawal sleeve is a steel part that threads into the threaded bore of the shaft to facilitate the removal of bearings with a tapered bore. It is used when the bearing is mounted with interference and cannot be removed with conventional pullers. MR Accesorios Industriales sells this series, with sizes for different shaft diameters.

The SKF withdrawal sleeve of the AH series is a key part for removing bearings with tapered bore without damaging the shaft or the bearing. It is used in industrial maintenance tasks where clean and safe disassembly is a priority. MR Accesorios Industriales sells this line, backed in the field.

The SKF AOH G series withdrawal sleeve is a mounting and dismounting component for bearings with a tapered bore. It is placed on the shaft and, by means of a precision lock nut, allows the bearing to be removed without damaging the inner ring or the seat. MR Accesorios Industriales sells this line, backed in the industrial sector.

The SKF HMV …E series hydraulic nut is a mounting and dismounting device that threads onto the shaft or adapter sleeve and generates oil pressure to expand the fitted part. It is used when the interference fit is too large to mount by impact or with a press, and allows work with control and without damaging the seat surfaces. MR Accesorios Industriales carries it as part of its mounting line.

SKF HMV references ending in /233983 identify spare seal kits for hydraulic nuts. The photo shows O-rings: the item listed is the sealing spare part, not the complete hydraulic nut.

The SKF HMVC …E series hydraulic nut is a precision tool used to mount and dismount bearings, sleeves and other components with a press fit on shafts or in housings. Its hydraulic design allows a controlled and uniform axial force to be applied, preventing damage to the parts and making work easier in tight spaces. It is a reliable solution for maintenance workshops and industrial plants that require fast and safe interventions.

The SKF MB series lock washer is a fastening component used together with a slotted lock nut to secure bearings and other elements on threaded shafts. Its design with an inner tab and several outer tabs allows positive locking: one tab fits into the shaft groove and another is bent into a notch in the nut. This prevents the nut from loosening due to vibration or rotation. MR Accesorios Industriales sells this series as part of its line of bushings and sleeves.

The SKF lock washer W series is a locking component placed between the adjustment nut and the bearing to prevent the nut from loosening due to vibration. Its design with an inner and outer tab allows locking the nut in the desired position. It is used in bearing assemblies mounted on shafts, where tightening safety is critical.

SKF MS designations correspond to lock clips for lock nuts. They are locking elements secured with a screw. They are identified by their full code and by the lock nut they work with.

The SKF inch adapter sleeve, SNW series, is a key component for mounting bearings with tapered bore on cylindrical shafts. It is widely used in applications requiring secure and adjustable fixation, such as in transmissions, pumps and industrial equipment. MR Accesorios Industriales sells this line.

The SKF hydraulic sleeve of the OH..H series is a key component for mounting and dismounting bearings with a tapered bore. It is used in applications where secure and precise fastening is required, facilitating maintenance tasks and reducing the risk of damage to the shaft and the bearing. Its design allows hydraulic pressure to be applied to achieve a firm and controlled fit.

The SKF hydraulic sleeve of the OH HTL series is a mounting tool designed to facilitate the installation and removal of bearings with a tapered bore. It works by means of injected oil pressure, which reduces effort and prevents damage to the bearing and the shaft. It is a practical solution for industrial maintenance workshops that need precision and care in every intervention.
