Bearing Service Tray

A foam-lined workshop tray that combines Unior's bearing puller kit and bearing press kit into a single organized assembly; slide hammer with extractor, bearing punches, and press discs sized for the bike-relevant cartridge-bearing range. The complete bearing service kit for a shop that builds and rebuilds wheels, services suspension pivots, and tears down full-suspension MTB linkages.

A cartridge bearing is a sealed unit press-fit into the hub shell, the suspension pivot, the headset cup, or the bottom bracket cup. Removing and installing it requires two tools: a puller (to pull the bearing out without damaging the shell) and a press (to push the new bearing in without damaging the bearing seal or the bearing race). The tray combines both into one fitted assembly so the bench has everything in one place for the bearing-service workflow.

What's in the tray

The foam-lined tray holds the components in fitted cutouts so each tool has a known position. The kit covers:

• Slide hammer with bearing extractor: the puller side of the kit. The slide hammer transmits a controlled impulse to the extractor's jaws, which grip the bearing's inner race from behind and pull it out of the shell.
• Bearing punches and discs sized for common cartridge-bearing OD/ID combinations: the press side. The punch transfers the press load from a hammer or a press handle onto the bearing's outer race, seating the bearing into the shell without loading the bearing's internal balls or seals.
• Drift block / receiver pieces for the press side: the receiver supports the back side of the shell while the punch presses the bearing in, distributing the load so the shell doesn't deform.

Where the tray fits

The bearing tray is designed to seat into the 2600A or 2600C workbench drawers; same dimensional standard as the rest of Unior's modular bench-organization line. A workshop running a 2600-series workbench gets the tray as a slide-in module that integrates with the bench's existing drawer-organization system.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The bearing service tray sits alongside Unior's wheel-truing stand and dishing-tool catalog as part of the wheel-build workflow; the bearing-service step is one of the load-bearing stops between hub teardown and rim-finishing-and-tension, and the tray puts the puller and press functions in one workshop motion.

Pro tip from our mechanics

The wrong bearing punch size is the most common cause of damaged cartridge bearings during installation. A punch slightly larger than the bearing's outer race transfers load onto the bearing seal instead of the outer race, which damages the seal on the first press. Use the punch sized to the bearing's exact OD, not “close enough.” The tray's organized cutouts make the right-size selection visible before the press starts.
