## Long description

Needle bearing for Tryton angle grinder models TMS23021 and TMS23020. This spare part is designed to support rotary components in the gearbox assembly, providing low-friction contact and stable rotation under radial load. It is intended as a direct replacement for worn or damaged bearings during repair and routine maintenance of compatible Tryton grinders used in workshops and home environments.
Advantages
The bearing provides a compact design with high load-bearing capacity for its size, allowing smooth rotation of the grinder’s gearbox components and helping to reduce wear on mating parts. Its needle-roll construction offers consistent radial stiffness and reliable performance under continuous operation. The part enables cost-effective repair by restoring proper alignment and rotational behavior without replacing larger assemblies.
Suitable for
 Repair of Tryton TMS23021 and TMS23020 angle grinders
 Maintenance of gearbox and rotating assemblies
 Workshop and home tool servicing
 Replacement of worn or noisy bearings
Key specifications
 Type: needle/roller bearing for radial load
 Fitment: bearing for angle grinder gearbox rotary elements
 Construction: needle rollers in a compact cage for reduced friction
 Function: supports shaft rotation and reduces play

How to use
Disassemble the grinder gearbox following the manufacturer's safety procedures and remove the worn bearing. Clean the housing and shaft surfaces, inspect for damage, and ensure correct seating dimensions. Press or slide the replacement needle bearing into position with appropriate tooling to avoid damaging the rollers or cage. Reassemble the gearbox, check shaft alignment and endplay, and test the tool at low speed before normal operation.
Usage recommendations
Use proper press-fit tools or bearing drivers to install the bearing without applying force to the rollers. Inspect surrounding gears and shafts for wear when replacing the bearing, and apply suitable lubricant if required by the grinder design to ensure long service life.
