RBC Bearings Incorporated (RBCBearings, RBC) has had a long tradition of innovation, commitment, and quality since the company was founded in 1919. 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 applications. > Heavy Duty Needle RollerBearings - Pitchlign RBC has been a pioneer in spherical plain bearing technology sinceinventing the fractured outer race design many years ago. Since that time, RBC has continued to...

r2r130Dd1d BCK Up to 300% improved service life provided by innovative lubrica- tion system. The patented system distributes lubrication to the load zone even when no load reversal exists and allows re- lubrication without removing the load. These bearings provide an increased life to many problem applications. Available in inch or metric sizes.RBC's DuraLubeЙ self-lubricating spherical plain bearings pro-vide long life in demanding applications. Grease-free operation is accomplished through the use of a durable PTFE liner system that reduces friction between the spherical surfaces of the...

Circular Lube ChannelsCircumferential GrooveInner RingSeal Outer Ring > ough applications in construction and material handling requires a spherical plain bearing with longer life, less maintenance and less downtime than standard spherical plain bearings. Abearing with total interchangeability to standard designs is preferred. RBC engineering developed theQuadLube > ή spherical plain bearing after observing the three predominant factors which contribute tothe failure of spherical plain bearings: Each factor contributes to a lack of lubrication in the load zone area which eventually allows...

The innovative design of the RBC QuadLube > interconnecting lubricating groove system ensures a more efficient distribution of the lubricant by providing channels that transport the grease throughout the entire bearing, including into the contact ar ea of the bearing under load. In cases of unidirectionalload or when lubrication intervals are missed, the groove system retains extra lubricant where it is needed for added margin of performance. In the dirtiest of environments the grooves and channels capture any dirt or debris and keep these contaminants away from the raceway surfaces.The RBC...

Advanced Seal Technology SpreadLock > ή Seals for spherical plain bearingsemploy double positive contacting lips to keep the dirt out and the lubricant in. Compare new SpreadLock > Seal technology with single or dou-ble lip designs oriented in one direction only. Positive, yet functional, sealing is one of theongoing challenges in bearing design. In our quest to develop the definitive seal that would work more effectively with our spherical plainbearings, we asked several tough questions to help establish the design priorities. How can we provide maximum protection against the entry of...

Advanced Technology Self-lubricating bearings are being utilized in skid steer, telehandler, off-road forklift, and wheel loader applications primarily on the cylinders, as well as on the pivot points of such equipment. The benefits of using these bearings include improved field reliability and lowered warranty costs. DuraLube Self-lubricating Spherical plain bearings has also reduced the cost of ownership by elimi- nating the need for zerk fittings, and costs associated with greasing and maintaining the bearings. RBC's DuraLubeٙ self-lubricating spherical plainbearings provide long life in...

Advanced Shock Load Protection The ImpactTuff > ή spherical plain bearing improvesresistance to shock loads by 300%! In many rugged applications where substantial impact loads are common, spherical plain bearings can break and chip, adding to the high cost of war- ranties. In particular, suspension components in off-highway construction vehicles have been sub- ject to abuse from impacting rocks or abrupt ter- rain changes. Often, the result is broken bear- ings resulting in costly machinery repair. Up to the Challenge The real challenge of the case carburized design is being able to...

A Clean Solution Designed specifically for applications that involvehigh levels of dirt or other contamination, the RBC CrossLube > ή spherical plain bearing utilizes the latest generation of lube groove design technology. While this system greatly improves lube distribution, it also facilitates relubrication purging to flush out wear debris and contaminants.The CrossLube > feature is particularly effective industy, highly contaminated environments, such as kingpin applications in farm machinery. > Engineered Solution The MillTuff bearing is a specially designed sphericalplain bearing. The...

The RBC ShimPack > ή double acting angular contact spherical plain bearing was developed to ease the installation procedures required onthe assembly line. Traditionally the bearing assembly was completed, clearance was measured and then the assembly was disassembled,shimmed and reassembled. With the RBC ShimPack > double acting angular contact spherical plain bearing, a spacer is preset and indi-vidually calibrated at the factory to provide the optimum amount of axial internal clearance. > The cover plate has to be bolted down until all clearance in the bearing is eliminated and gap X...

ή double acting angular contact spherical plain bearing in articulated joints in place of a tapered rollerbearing offers many advantages. The misalignment capable B-DSA-3 design means that costly line boring is no longer necessary. Alignment becomes less critical allowing the relaxation of bore tolerances and an easier assembly. Assembly also becomes easier asaxial clearance no longer has to be set during installation. Dirt and water, which would destroy a roller bearing, are more easily toler-ated with the B-DSA-3 design. Misalignment from shaft and housing bore wear have less effect on...
