Linear bearings often require lubrication in order to reduce rolling resistance and to minimize sliding friction between rolling elements, raceways, and cage. Since linear bearings are often fabricated as self-contained slides, grease is a common lubricant, and in the case of point-contact ball slides, often no lubricant is used.
SKF spherical roller thrust bearings have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers .
Correct lubrication is critical to bearing performance. For more information on our standard oils and greases, please see our LUBRICANT TABLES. Lubrication provides a thin film between the contact areas in a bearing to reduce friction, dissipate heat and inhibit corrosion on balls and raceways.
Hardened Crown Roller Bearings (PAC) PBC Linear’s hardened crown rollers are a superb choice for low-cost linear motion. The rollers come pre-assembled and are self-aligning for simple installation. Hardened crown rollers are great for point-to-point applications, and ensure strong, sturdy and long-lasting linear motion.

Posted on: August 17, 2015. Lack of lubrication is generally regarded as the number one cause of bearing failure. For recirculating linear bearings, such as profiled rail guides and ball screws, lubrication separates the bearings (ball or roller) from the raceways, minimizes friction and wear, dissipates heat, and prevents corrosion.
Minimize Corrosion and Maximize the Life of Linear Roller Bearing Systems Introduction Linear roller bearing systems offer distinct advantages in applications where high speed or quick change of direction is required. Due to the fact that their diameter is larger, they also perform well in contaminated environments where they roll over or “push” particulate from […]
Redi-Rail Linear Guide (Metric) - RR Rail and RRS Carriage. Redi-Rail ® Metric Rails are precision machined for optimum accuracy and parallelism. An aluminum rail integrated with hardened steel races ensure a lightweight design without sacrificing strength.
Depending on the design, tapered roller bearings are separable and components of same-sized bearings are fully interchangeable. For example, single row tapered roller bearings are separable , i.e. the inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup). This facilitates mounting, dismounting and ...

Roller Lubrication. All smaller rollers (in the Redi-Rail®, Integral-V™, V-Guide, Commercial Rail, Hardened Crown Roller families, and smaller diameter Hevi-Rail® bearings) are lubricated for long life. No additional lubrication is necessary. The rollers are sealed (or shielded) against the operating environment to prevent egress of lubricant and ingress of contaminants.

Linear motion systems include linear motion bearings, slides, and rails as components, and are used in a wide variety of applications. Linear motion products include ball screws, slide rails, roller tables, ball slides, ball splines, guides, actuators, cross roller guides, and lead screws.
Did you know that good lubrication avoids 55% of premature bearing failure? Significantly increase the service life of your bearings by applying lubrication correctly. Apply a lubricating film, also called an oil film , between the rolling elements and the raceways of the bearing. Benefits of lubrication: reduced wear and risk of seizure.
Lack of bearing lubrication is generally regarded as the number one cause of linear-bearing failure. For recirculating linear bearings such as profiled rail guides and ball screws, lubrication separates the bearings (ball or roller) from the raceways, minimizes friction and wear, dissipates heat, and prevents corrosion.
Conventional greases ╳ Consistent grease with a mineral oil and/or synthetic oil base with thickener as well as active ingredients or additives. See DIN 51 825 part 1 for demands on greases, grease type K, operating temperature range -20 to 140°C or DIN 51 825 part 2, for grease type KT. have metal soaps as thickeners and a mineral base oil Figure 3.
Proper lubrication for rolling bearings is essential for reliable operation. Given that some leading bearing companies have stated that incorrect lubrication can account for more than 30 percent of bearing failures, lubrication is a key influence that can make or break bearing service and life. The ...
Most roller bearings use cylinder whose length is slightly greater than its diameter. Roller bearings have higher radial load capacity compared to ball bearings but higher friction and a low axial capacity under axial loads. 2.1. Applications of roller bearings: Roller bearings are used in rotary applications to replace sliding movement with ...
