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 expandable collets, a threaded press spindle, and press adaptors 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 expandable collet, which grips the bearing's inner race from behind and pulls it out of the shell.
• Bearing press spindle and adaptors sized for common cartridge-bearing OD/ID combinations: the press side. The spindle's two threaded handles (one with a quick-release system) draw the sized adaptor squarely against the bearing's outer race, seating the bearing into the shell without loading the bearing's internal balls or seals.
• Plastic-coated press protectors for carbon surfaces: two different-sized plastic-coated adaptors sit between the press and delicate surfaces, so carbon frames and components aren't marked during bearing installation.

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 sponsors professional road and mountain-bike race 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.

FAQ

Which bearing sizes can the SET-2600E-US press and pull? The press side carries 21 adaptors for standard cartridge bearings: 608, 1526, 6000, 6001, 6802, 6803, 6804, 6805, 6900, 6901, 6902, 6903, R6 and 28x17 (Hope), plus BB30, the Press-Fit bottom bracket standards and SRAM DUB (29x42). The puller side runs six expandable collets covering 6.5-8, 10-12, 12-15, 17-20, 22-28 and 30-36 mm inner diameters.

Will the tray fit my workbench drawer? Yes, if the drawer takes Unior's wide-format trays. The foam tray is a full-width (1/1) module with a 562 x 570 mm footprint, 30 mm deep, sized for the wide drawers of the 990WD7 tool chest built into the 2600A and 2600C workbenches. The 2600C Master Workbench ships this tray as one of its standard modules.

Is the press safe for carbon frames and components? Yes. The kit includes two different-sized plastic-coated press protectors that sit between the press and the surface, so carbon stays unmarked while the bearing seats. The press itself is a threaded spindle with two handles, applying steady screw force rather than impact.

How does bearing removal work with this kit? You insert the right-sized expandable collet through the bearing bore and tighten it so it expands and grips the inner race from behind. The heavy-duty slide hammer then drives the bearing out of the housing with controlled impacts, without damaging the shell.
