6305/22 22x62x17mm Non‑Standard Deep Groove Ball Bearing – Automotive Transmission & Driveline Component

Product Overview

The 6305/22 is a single‑row deep groove ball bearing engineered for automotive and industrial applications that demand a non‑standard bore size. With its unique dimensions of 22x62x17mm, this bearing provides a versatile solution for transmission assemblies, driveline components, and other mechanical systems where standard 6305 bearings (with a 25mm bore) do not fit.

Manufactured from high‑grade GCr15 chrome steel, the 6305/22 features an open design (no seals), a robust steel cage, and C3 radial internal clearance. Its non‑standard configuration allows engineers to optimise shaft and housing designs without compromising load capacity or rotational performance. Built for reliability under continuous operation, this bearing is an excellent choice for both original equipment and aftermarket replacements in passenger cars, commercial vehicles, and industrial gearboxes.

Design & Construction Features

Non‑Standard Bore Size – The 6305/22 offers a custom 22mm inside diameter, providing design flexibility for shafts that do not conform to standard 6305 dimensions. This allows direct replacement or integration into bespoke housings without costly re‑engineering of adjacent components.

Deep Groove Raceway Geometry – Optimised for high radial load capacity and low running friction, the deep groove design also supports moderate axial loads in both directions, making it suitable for gear shafts, input/output shafts, and pulley assemblies.

GCr15 Chrome Steel – Manufactured from vacuum‑degassed, high‑carbon chromium steel, the 6305/22 delivers excellent hardness (HRC 60‑65), superior wear resistance, and outstanding rolling contact fatigue strength, ensuring long service life even under fluctuating loads and high‑speed rotation.

Open Design – Without integrated seals, this bearing is ideal for applications where the system provides its own lubrication (oil bath or splash) and where operating temperatures or speeds may exceed the limits of rubber seals. The open configuration also simplifies cleaning and relubrication in maintenance‑friendly environments.

Robust Steel Cage – The stamped steel cage offers high strength, heat resistance, and dimensional stability. It is particularly suited for heavy‑duty and high‑temperature applications where nylon cages may be less durable.

C3 Radial Internal Clearance – The C3 clearance ensures stable operation under thermal expansion and interference fits, preventing excessive preload and heat buildup during extended running periods.

Materials & Quality Assurance

All 6305/22 bearings undergo 100% quality inspection, including dimensional accuracy, radial runout, noise and vibration testing (V3/V4 standards available), and torque measurement, in compliance with ISO 9001 and IATF 16949 quality management systems.

Applications

The 6305/22 is specifically designed for automotive and industrial drivetrain applications where a 22mm bore is required:

• Automotive Transmissions – Main shafts, countershafts, and lay‑shaft bearings in manual and automatic gearboxes

• Transfer Cases & Differential Assemblies – Supports rotating components under combined radial and thrust loads

• Industrial Gearboxes – General‑purpose shaft support in speed reducers and multi‑speed drives

• Agricultural & Construction Equipment – Transmission and PTO (power take‑off) systems

• Electric Motors & Pumps – Where open bearings are preferred for oil lubrication or high‑speed operation

• Pulley & Belt Drive Systems – Idler and tensioner applications with separate lubrication circuits
