Timkens spherical plain bearings (SPBs), or bushings, are metal-on-metal bearings consisting of a spherically ground inner ring housed in a mating outer ring without any rolling elements. While all plain bearings are precision ground and made from through-hardened steel, custom orders are available and can include special materials, clearances, surface finishes or configurations to accommodate unique applications. Our SBT and SBDT designs feature lubricating holes and grooves in the outer ring for easy relubrication through the housing. Available in inch and metric sizes from 12.7 mm to 600 mm (.5 in. to 23.622 in.) bore Design Attributes Rings manufactured from hardened steel help deliver consistent, reliable performance.Phosphate-treated rings coated with molybdenum disulfide (MoS2) minimize friction of contacting surfaces.Simplified housing and shaft designs reduce installation time.

All cylindrical roller bearing configurations (except RAA) provide precision control of the rollers for operation over a wide range of speeds with precision-ground, double-ribbed guide flanges on one ring. These roller bearings are found in turbine engine mainshaft, transmission and gearbox applications with high radial loads. Design Attributes: RF and RJ configurations are designed for applications requiring axial position control or limited thrust capabilities in one direction.For applications operating at higher loads and speeds, the RJ configuration is designed for easier lubrication with an oil jet onto the inner race.Types RU and RN are full-floating configurations that allow limited axial motion during operation. RN is less prone to slip or skid under lighter loads or varying loads at high speeds. RU is easier to lubricate under heavier loads.Types RUS and RNH bearings are used in integral designs where the rollers run directly on a hardened and ground shaft or housing. Performance characteristics are similar to RU and RN.The RAA configuration has single-ribbed inner and outer rings and performs under low speeds or oscillating conditions. It has high guide flanges to accept some thrust in one direction.

Based on the design of the AP bearing, Timkens AP-2 rail bearing is designed for heavier loads. It reduces bearing set outs fuel cost and bearing failure due to water ingress. It also reduces component wear rejection and axle fillet damage, decreasing potential axle failure and ultimately reducing the occurrence of axle grooving. Design Attributes: Reduces bearing failure due to water ingressReduces bearing set outsReduces fuel costsReduces component wear rejectionReduces axle fillet damageDecreases potential axle failureApplications: Rail Freight Cars

Timken Formed Hub is an integrated wheel bearing assembly that can bolt directly onto corners, eliminating the need for conventional components like washers, spacers and nuts. The design enables lower total system cost, commonization opportunities, improved performance, reduced weight and lower warranty costs. Design Attributes: Designed with nearly 75% fewer components, reducing assembly time and lowering costs for sourcing, inventory and assembly.Engineered for driven and non-driven wheels, replacing the conventional 42 (dead) spindle.Features an advanced sensor and sensor technology for superb performance.Holds bearing setting more consistently than traditional thread and nut designs.The resulting system stiffness reduces rotor runout and improves brake performance.Reduces weight by up to 20% per assembly compared to conventional wheel end solutions.Self-clamped design eliminates high stress in the spindle and CV joint, reducing overall warranty costs caused by bearing wear and failure.

Timkens high-precision tapered roller bearings consist of carefully matched components that offer an added degree of fine-tuning in the bearing setting and adjustment procedure to maximize customer machine productivity. Timken manufactures high-speed designs with a variable preload capability for optimum performance. Timken also manufactures Precision Plus bearings having an overall radial runout less than a single micron.

The Generation 3 hub and bearing assembly is an integrated bearing assembly that offers design flexibility and bolt-on simplicity and features active sensing technology. Generation 3 improves stiffness and brake performance, reduces weight and envelope size, lowers assembly costs and reduces warranty claims. Design Attributes: Integrated raceway and hub increases stiffness as much as 30 percent over conventional systems. Also eliminates the discrete race variables between the bearing and hub, providing a closer preload setting range.Narrow overall package width and reduced radial section thickness lowers unsprung weight, improving vehicle maneuverability and fuel efficiency.Features a pre-sealed, pre-greased and pre-set bearing package design with integrated sensing technology for anti-lock braking systems, total traction control and vehicle dynamics systems.Hub-forming technology reduces strain on components and the costs associated with purchased parts and labor. Also allows for commonization between driven and non-driven designs.Fully serviceable wheel speed sensor is internally mounted and protected from road hazards, debris and potential damage.
