The LBCR D from SKF is a linear bearing built to carry loads along cylindrical shafting while keeping movement smooth and controlled. Ball cage and sealing are combined in one unit, so it fits applications where guidance accuracy and protection from the surrounding environment both matter. MR Industrial Accessories supplies this series to maintenance and purchasing teams throughout the United States and Latin America.
Reading the code helps when you are matching a replacement. LBCR is the SKF series identifier for a linear bearing with ball cage and built-in seals. The digits that follow give the shaft size in millimeters, such as 20, 30 or 40. The trailing D marks the double-sealed version, which holds lubricant in place and keeps contaminants out. An LBCR 20 D, for example, fits a 20 mm shaft and carries double sealing.
Machine tools, automation equipment, conveyors, handling devices, presses, injection molding machines and packaging lines are common homes for these bearings. Because they handle radial loads and moments, they suit linear guide arrangements that call for stiffness and accuracy. Automotive, food, pharmaceutical and metalworking plants use them in production equipment.
Selection starts with shaft diameter, then moves to the load the bearing will see, the travel speed and the working environment. Choose the double D seal where dust or moisture is present. Shaft and housing alignment must be accurate, since misalignment speeds up wear. Correct lubrication and mounting with the right tools also affect how long the bearing lasts, so check the technical data for each application.
On interchangeability, SKF LBCR D bearings can stand in for other brands of similar dimensions when tolerances and load ratings line up. Compare housing height and seal type as well as shaft diameter. MR can review your equipment and point to the option that fits.

Frequently asked questions
- What does the D suffix indicate on an LBCR bearing?
- It identifies the double-sealed variant, which retains lubricant and blocks contaminants. That makes it a fit for dusty or humid conditions.
- How do I pick the right LBCR size?
- Measure the shaft where the bearing mounts. The number in the designation, such as 20, 30 or 40, is that diameter in millimeters. Load and speed requirements should be checked as well.
- Can SKF LBCR D bearings be swapped with other brands?
- They may work in place of equivalent linear bearings, but tolerances, load capacity and seal type need to be verified. Contact us and we will help confirm compatibility.
