Parts supplied from our European supplier

They normally dispatch within 7–10 working days, and are then sent on by express courier like anything else. Nothing ships to you direct from Germany — it comes to our Arlesey workshop first, so you deal only with us for returns and warranty.

Koyo Deep Groove Ball Bearing 6305 2RS C3 – 25×62×17mm
The Koyo 6305 2RS C3 is an open deep groove ball bearing with rubber seals on both sides and C3 internal clearance, measuring 25mm bore × 62mm OD × 17mm width. Deep groove ball bearings are the most widely used bearing type in automotive gearboxes, offering versatility, durability, and the ability to accommodate both radial and axial loads. The C3 clearance designation indicates greater-than-normal internal play, making this bearing well suited to applications with interference fits or elevated operating temperatures.

Part number(s): 6305 2RS C3 · 63052RSC3 · 6305 2RS C3 TN9 · 6305 TN9 2RS C3 · 6305 T1X DDU C3 · 6305 2RS/C3 FG · 08133-63057 (Suzuki) · 08133-63050 (Suzuki)
What is C3 internal clearance and why does it matter?
C3 clearance is greater than the standard (CN) clearance. This accommodates thermal expansion of the shaft and housing during operation, and allows interference fits without clamping the bearing rolling elements. It is the most common choice for gearbox bearings that run warm or are press-fitted.
What does 2RS mean?
2RS means the bearing has rubber contact seals on both sides. These retain grease and exclude contamination, making 2RS bearings pre-lubricated and suitable for applications where re-greasing is not practical.
Is Koyo a quality brand for gearbox use?
Yes. Koyo is the bearing division of Jtekt Corporation (Toyota Group) and manufactures to OEM quality standards. Koyo bearings are used as original equipment in numerous automotive transmissions worldwide.
