Axial Cylindrical Roller Bearing

What Is an Axial Cylindrical Roller Bearing?

An axial cylindrical roller bearing is a thrust bearing that uses short, roller-shaped elements instead of balls between its two flat washers. Because a roller touches the washer along a line rather than at a single point like a ball does, this bearing can spread out a much heavier load and resist bending or flattening under pressure.

This higher load capacity comes with a trade-off: axial cylindrical roller bearings generally run at lower speed than a ball-type thrust bearing, since the rolling and sliding action of a cylindrical roller creates more internal friction and heat at high revolutions. That is exactly why this bearing type is chosen for slow, heavy-duty presses and mills rather than fast-turning spindles.

Most versions are supplied as a caged roller and cage assembly, meant to be fitted between a shaft washer and a housing washer that are ordered separately, giving the customer flexibility over exact bore and outer diameter needs.

Axial Cylindrical Roller Bearing vs Needle Roller Thrust Bearing: What Is the Difference?

A needle roller thrust bearing uses very thin, long needle rollers arranged in a cage, giving good load capacity while keeping the overall bearing height low, which suits tight axial space. An axial cylindrical roller bearing uses shorter, thicker rollers with a larger diameter, giving it a higher load rating and longer working life under heavy, continuous thrust, though it needs more axial space to fit. Where housing space is very limited, the needle type often wins; where raw load-carrying strength matters more than compactness, the cylindrical roller type is the stronger option.

Types of Axial Cylindrical Roller Bearings

• Single Direction Caged Roller Bearing (81100 Series): This standard type carries thrust load from one direction only and uses a cage to keep the rollers evenly spaced, suiting general press and gearbox duty.
• Heavy Series Caged Roller Bearing (81200/81400 Series): Built with larger rollers and a thicker cross-section, this version is chosen for the heaviest presses, mills, and forging equipment.
• Bearing and Washer Kit (K-Prefix Sets): Supplied as a complete set with matched shaft and housing washers, this option saves the customer from sourcing washers separately.
• Cylindrical Roller Thrust Bearing with Sphered Seating: A slightly curved seating washer allows small self-alignment, protecting the roller set from uneven load caused by minor shaft misalignment.

Benefits of Choosing the Right Axial Cylindrical Roller Bearing

• Very High Load Capacity: Line contact between roller and washer spreads heavy load better than a ball-type bearing.
• Strong Under Shock Load: The solid roller and washer design resists sudden, heavy pressing force well.
• Good for Slow, Heavy Duty: Well suited to presses and mills that run at lower speed but carry very high load.
• Flexible Washer Options: Separate or kit-supplied washers let buyers match the exact bore and outer size needed.
• Long Life Under Repeated Load: Hardened, precision-ground rollers resist wear even after years of repeated pressing cycles.
• Cost-Effective for Heavy Jobs: Often more economical than oversizing a ball thrust bearing to reach the same load rating.

Country-Wise Use of Axial Cylindrical Roller Bearings in Our Export Network

Heavy industry needs in each export market shape how axial cylindrical roller bearings are typically used. Here is a short country-by-country look:

How to Select the Right Axial Cylindrical Roller Bearing

• Calculate Peak Thrust Load: Heavy or shock-prone jobs usually call for the heavy series over a standard caged type.
• Check Available Axial Space: Compare the bearing height against your housing depth before finalising the series.
• Confirm Running Speed: Very high speed needs may point toward an angular contact ball bearing instead.
• Decide on Washer Sourcing: Choose a complete kit if you prefer matched washers included with the bearing.

Common Mistakes to Avoid When Choosing an Axial Cylindrical Roller Bearing

• Running It Above Rated Speed: Excess speed causes rapid heat build-up and early roller and washer wear.
• Ignoring Washer Flatness: An uneven or worn washer surface leads to uneven load across the rollers.
• Mismatching Bearing and Washer Sizes: Separately sourced washers must match the roller set exactly to avoid poor contact.
• Under-Estimating Shock Load: Choosing a standard series where sudden heavy load is expected shortens bearing life quickly.

Simple Maintenance Tips for Longer Life

Check for unusual heat build-up around the bearing housing during routine rounds, since this often points to speed or lubrication trouble. Inspect the washer surfaces for pitting or flat spots whenever the bearing is opened up for service, as damaged washers wear out a new roller set quickly. Keep to the recommended heavy-duty grease schedule, since high load pushes lubricant out of the contact zone faster than in light-duty bearings.
