Tapered bearing. Recent design changes to this company’s tapered roller bearings have resulted in improved performance and durability. A new retainer design provides greater oil retention and improves lubricity on the roller surfaces. This change minimizes friction and evenly distributes lubrication for longer bearing life. The cup and cone angles remain interchangeable with those of comparable manufacturers. Test results show more than eight times L10 life, and at competitive prices. An online engineering catalog is available with both inch and met-ric sizes. Basic load ratings and tolerance data are given. Manufacturing facilities are rated QS9000.

Spherical bearings. Five basic types of spherical plain bearings are offered: Standard Radial, accommodating misalignment for heavy radial or thrust loading; Extended Inner Ring, eliminating locational spacers; High Mis-alignment, featuring a heavy cross section; Angular Contact, single acting for unidirectional thrust and combina-tion loads; and Self-Lubricated for low maintenance with Teflon, dry film or injection-molded polymer lubrication.

Bearings guide. The 28-page LEG SlimLine Design Guide for low-profile LEG thrust bearings provides com-ponent descriptions, feature and benefits, lubrication and performance comparison charts and selection instruc-tions for 6-, 8- and 11-shoe bearings. The equalizing bearing features a Leading Edge Groove that lowers frictional losses and lube oil requirements while reducing oil film temperatures.

Lube system. The 780S-SS lubrication system provides precise distribution of medium-viscosity greases and other lubricants to spring, tracks, hinges and other hardware. Only 4-in. long by 1-in. dia., the spray valve uses LVLP air to put lubricant exactly where it is needed and cuts lubricant use by 50% or more. A compact, micro-processor-based Valvemate controller simplifies setup and operation for fine-tuning. EFD Inc, E Providence, RI.
