Solid aluminum construction for strength, durability and rust resistance — built to withstand repeated use while protecting the tool from corrosion. Designed to install wheel bearing races and seals cleanly: the shape and tolerances make it easy to press races and seals into place without damaging the barrel or mandrel housing. Broad compatibility: fits most standard bushings and wheel bearings. Reversible discs allow you to flip them to drive seals or to support races during installation, reducing the need for multiple adapters. Reliable performance: maintains concentric installation to reduce seal and bearing damage, helping prevent leaks, premature wear and the cost of rework. How it solves common problems Prevents damage to housings and seals: precise contact surfaces and aluminum construction avoid burrs and deformation that occur with improvised tools. Saves time during service: one set handles a wide range of common sizes and can be quickly reversed to switch from installing races to driving seals. Reduces corrosion and wear on the tool itself, so it stays accurate and dependable over many jobs. Typical applications Automotive wheel bearing replacement: install bearing races and seals in passenger cars without marring the barrel or mandrel housing. Motorcycle maintenance: press in wheel seals or bushings on front and rear wheels using the reversible discs for seal driving. General bearing and bushing service: suitable for small machinery, ATVs or any equipment that requires precise installation of bearings or seals. What to expect Durable, rust-resistant aluminum construction for repeated shop use. Fits most standard bushings and wheel bearings; flip the discs to drive seals. Cleaner, more consistent installations that protect components and reduce rework.
