Medway B5/25MM-3GS-2Z Kart Axle Bearing – 25 × 52 mm, 2Z Shields, C3 Clearance, 3 x M6 Grub Screws – 25mm Axle, 52mm Carrier

The Medway B5/25MM-3GS-2Z is a 25mm bore kart axle bearing running in a 52mm carrier, with an extended inner race carrying three integral M6 grub screws that clamp the bearing directly to the axle. The outer ring is crowned to a spherical profile, so the bearing self-aligns inside a standard kart bearing cassette rather than fighting against small mounting misalignments. C3 internal clearance gives the races room to expand as the axle heats up, and 2Z metal shields keep track dust, rubber debris and grit out of the raceway without the drag of contact seals. Made in the UK by Medway Power Transmission Ltd, formerly Dunlop BTL. Supplied new as a single bearing.
