The 25 mm (~1") Spherolinder series is our most popular offering. Its static load carrying capacity is almost 2 tons per spherolinder - but due to its small size is still affordable and buys peace of mind in terms of margin and resistance to impact during assembly.

The 10 mm (~0.4") Spherolinder series is meant for use in smaller applications. Its static load carrying capacity is more than 250 kg per spherolinder, which is a good working point for "desktop applications" and optical tables.

In either size, the hardened 440C ball bearing steel is ideal for repeatable assembly applications and cyclic hertzian stress, provides resistance to incidental surface damage, and shows practically no surface wear.
