Today, RBC Bearings has grown into a world-class manufacturer of standard and custom- engineered bearings and related products, with a product focus on research, testing, and development of the best product for specific RBC Bearings, with facilities throughout North America and Europe, provides bearings and precision products for applications in the con- struction, mining, material handling, transportation and off-highway equipment, robotics and automation, farming, machine...

Self-lubricating Rods Ends Heim produces metal-to-metal rod ends and self-lubricating rod ends. All metal-tometal rod ends, including brass insert four piece types, require regular lubrication. This can be accomplished by splash or immersion oil lubrication, or by greasing through optional lubricators (grease fittings). Self-lubricating types are used where relubrication is not practical, or in applications where relubrication is not desirable, such as on food processing machinery or in clean environments. Heim self-lubricating rods ends are available with bonded PTFE fabric liners, or with...

• Angles of misalignment for series: STUDS STATIC RADIAL LOAD ROD ENDS The maximum static radial load permissible for a rod end depends on three factors: race material compressive strength; rod end head strength; and shank strength. The maximum static radial load is determined by taking the lowest of the three following values: • Race material compressive strengths (R) R=ExHxX MATERIAL STRESS TABLE Material Allowable Stress (PSI) Brass Aluminum Bronze 300 Series Stainless Steel Low Carbon Steel Alloy Steel HM HM C HM M HME M 30,000 35,000 35,000 52,000 140,000 cartridge type construction H...

MISALIGNMENT SPECIFICATIONS The angle of misalignment in a spherical bearing is calculated somewhat differently from that of the rod end because the housing is not spherical. There are three different types of mountings in which these bearings may be used as shown, and the angle of misalignment is governed by the type of mounting adopted. Shown below are the common mountings for spherical bearings and the corresponding formula for calculating the Sleeve Bearings Sleeve Bearings Heim manufactures sleeve bearings in a wide range of materials and sizes aerospace applications.
