Main description

The FAG 1203 TVH 17x40x12 self aligning ball bearing is a compact and versatile rolling bearing designed for applications where perfect shaft alignment cannot be guaranteed.

A self aligning ball bearing is engineered to automatically adjust its position during operation, compensating for angular deviations between the shaft and housing. This significantly reduces mechanical stress and increases system reliability.

The 1203 TVH belongs to a widely used bearing series available across global bearing shop online platforms and B2B supply chains. It is often compared with equivalents such as SKF 1203, making it a standard solution in industrial applications.

Its double row ball construction ensures better load distribution, while the spherical outer raceway allows continuous alignment correction. This reduces wear and improves durability under dynamic conditions.

The polyamide TVH cage enhances performance by reducing friction and improving lubrication efficiency. This results in smoother, quieter operation and longer service intervals.

With dimensions 17x40x12 mm, this bearing is ideal for compact machinery and light to medium duty industrial applications where space is limited but reliability is essential.

FAG manufacturing quality ensures precision, durability and long service life, making this bearing a trusted solution for OEM manufacturers, maintenance teams and industrial distributors.

This product is designed for B2B customers seeking reliable and cost effective solutions for misalignment compensation.
