Bearing accessories

Bearing accessories are a range of components and tools that are essential for the correct mounting, securing, protecting, and monitoring of bearings, ensuring they run smoothly, reliably, and with maximum efficiency.
Mounting and Securing Accessories
These components are vital for the correct installation and secure operation of bearings on shafts or within housings.
Adapter Sleeves: The most common accessory, used to mount bearings with a tapered bore onto a cylindrical shaft. They are easy to install and often include a locknut and washer.
Withdrawal Sleeves: Used to dismount bearings with a tapered bore from a tapered shaft seat.
Lock Nuts and Washers: These are used to securely position bearings and sleeves axially on the shaft and prevent loosening under vibration. Lock washers feature bent tabs for positive locking.
Thrust Washers/Rings: Used to fix a bearing within a housing or on a shaft and distribute axial loads, especially with needle or cylindrical roller thrust bearings.
Retaining Rings/Snap Rings: Used to maintain the position of a bearing and prevent lateral movement within a housing or on a shaft.
Protection and Sealing Accessories
These accessories protect the internal components from contaminants and maintain lubrication levels to extend service life.
Seals and Shields: Provide a barrier against dust, dirt, moisture, and debris. Types include metal shields (non-contact), rubber seals (contact), felt seals, and labyrinth seals.
End Covers/Caps: Used to close off the ends of bearing housings (like pillow blocks) for added protection and safety.
Gaskets and O-Rings: Used with bearing housings to create a tighter seal and prevent leakage or ingress of contaminants.
Installation, Dismounting, and Maintenance Tools
Using the correct tools ensures proper handling and prevents damage to the bearings or associated equipment during installation and removal.
Bearing Fitting Kits: Mechanical tool sets (including impact rings and sleeves) used for the cold mounting of small-to-medium sized bearings to ensure even force transmission.
Bearing Pullers: Tools (two-jaw, three-jaw, internal, hydraulic, or separator plates) used for safe and efficient mechanical dismounting of bearings without damage.
Induction Heaters: Devices used for the hot mounting of larger bearings by heating them quickly and evenly, causing expansion and easy fitting onto a shaft.
Hydraulic Tools: Hydraulic nuts, pumps, and pushers used for the effortless mounting or dismounting of large or tightly fitted bearings.
Lubrication Units and Adhesives: Includes lubrication equipment (pumps, grease nipples) and assembly pastes/adhesives to prevent fretting corrosion and ensure a secure fit.
Monitoring Accessories
For optimal performance and preventative maintenance, accessories for condition monitoring are available:
Vibration Measuring Instruments: Devices to monitor the vibration levels of bearings, which can indicate potential problems or wear.
Temperature Meters: Instruments to check bearing temperature, as overheating is a common sign of issues.
Speedometers/Tachometers: Devices used to measure the operating speed of the shaft and bearing assembly.
