The 70 Mu is the first caster of its kind. It utilizes one high-precision chrome steel radial ball bearing per caster, and two self-lubricating journal bearings in an efficient arrangement that allows for exceptionally smooth operation and twice the load rating of typical “high-capacity” chair casters, yet with lower costs of production and 30% less weight as compared to our 70 Okina Mu caster. This is the size most often associated with typical office chairs, tables and case goods. Select our 11mm friction sleeve stem mount for chair sockets, and plate mounts or threaded stems for case goods as necessary.

All wheels come in sets of 5

The 70 Mu is the first caster of its kind. It utilizes one high-precision chrome steel radial ball bearing per caster (for linear motion), and two self-lubricating journal bearings (for independent tire rotation) in an efficient arrangement that allows for exceptionally smooth operation and twice the load rating of typical “high-capacity” chair casters. Because of this hybrid bearing arrangement which lowers cost of production and reduces weight by 30%, the aperture on the 70 Mu is 17% smaller than the 70 Okina Mu. This is the size most often associated with typical office chairs, tables and case goods. Select our 11mm friction sleeve stem mount for chair sockets, and plate mounts or threaded stems for case goods as necessary. Estimated load capacity of 150 lbs. per caster (5 casters = 750 lbs., 4 casters = 600 lbs.). Covered by US patent 8561258. International patents pending. Certified compliant with BIFMA X5.1 durability standards for office chairs.

    I’ve just purchased 2 black 70 Mu for my mom’s office chair and 70 Okina Mu for my Herman Miller Black Aeron Chair. Looks amazing. The casters wheels are solid and easy to install. Going to order another set for my brother. But this time… might want to get the Grey color.

    Second set of 70 Mu, this one for the office. Upgraded my floor mat and stock wheels on my Hon chair seemed sluggish.

    No more, these casters are great. Everything is smooth as silk. Even went to red for the office to be able to tell if someone ‘borrows’ my chair.
