The Optimal Choice for Heavy Duty Linear Bearing Applications
Roller Pillow Blocks are an exceptional choice for roller bearing needs, particularly in heavy-duty applications across various industries. They are comprised of an anodized aluminum body and coated steel rollers, with a recommended shaft of carbon steel. Engineered for high performance and robust functionality, these pillow blocks are designed to support substantial loads, ensuring reliable operation in even the most demanding settings.
Available in single, double, and twin configurations in both inch and metric sizes, PBC Linear pillow block bearings offer versatility along with several features tailored to support heavy loads and high-speed operations. Whether your project involves high-speed movements, exposure to contaminants, or extreme temperatures, PBC Linear Roller Pillow Blocks deliver unmatched performance for applications with shaft sizes from 0.5" to 3” and 16 to 30 mm.
Heavy Duty Performance: Double Roller Pillow Blocks can support up to 12,500 lbs, making them ideal for applications requiring high load capacities. The higher load ratings permit you to use a smaller size pillow block allowing customers to save money on shafting.
Enhanced Speed Capabilities: These roller bearings can travel up to 7.62 m/s (25 ft/s), which is 2.5 times faster than traditional ball bearing systems.
Superior Alignment and Adjustability: The self-aligning feature in roller pillow blocks accommodates misalignments in joined shafts and allows for adjustable clearance to meet specific operational demands. Roller pillow blocks can handle a half of a degree in misalignment.
Excels in Extreme Conditions: In contaminated environments, the roller bearings push particulates out of the way or roll seamlessly over them and they are suitable for up to 392°F in high-temp models.
Corrosion Resistance: Constructed with corrosion-resistant materials, these roller bearings are suitable for harsh environmental conditions.
Interchangeable Standards: Ensures our roller bearings are compatible with industry-standard bearings, allowing for seamless integration into existing systems.
Rebuildable Design: Promotes sustainability and cost-effectiveness through the ability to rebuild worn out or damaged roller pillow blocks rather than replace.
Single Roller Pillow Blocks ensure durability and continued performance under stress in applications with shaft sizes from 0.5” to 3” and dynamic load ratings up to 6,260 lbs.
