Self-aligning spherical bearings -- igus inc.

 The igubal spherical bearings are self-aligning components — rod ends, clevis joints, flange bearings, pivot bearings, and pillow blocks — made of high-performance plastics. The self-lubricating bearings damp vibrations and operate in liquids, chemicals, dirt, or dust. The devices adapt to angular deviations and can replace special housings. The bearing’s housing is made from igumid D, a highly shock-resistant plastic, and its spherical balls are made from iglide L280 material. igus inc., Box 14349, East Providence, RI 02914, (888) 803-1895, www.igus.com
