The SKF LBBR LS series covers linear ball bearings that run on cylindrical shafts, providing guided motion with low friction. Each unit uses a cage and an outer sleeve, and the LS version adds sealing at both ends. MR Industrial Accessories supplies this line to maintenance and purchasing teams in the United States and Latin America, and can help you match the bearing to your load, speed and working environment.
Reading the part number tells you most of what you need. Take LBBR 10-2LS or LBBR 30-2LS: LBBR is the series, the number after it is the shaft diameter the bearing fits, and 2LS means double-lip seals at both ends. Those seals hold lubricant in and keep dust, chips and moisture out. Once you know the code, ordering a replacement is straightforward.
You will find these bearings in machine tools, packaging lines, pick-and-place units, presses, measuring equipment and general automation. They also show up in test rigs, manipulators and gantry axes. Because they handle radial loads and moderate moments, they suit repetitive motion. MR Industrial Accessories supplies them for both new projects and replacement.
Selection comes down to shaft diameter, expected radial and axial load, travel speed and the surrounding conditions. In dusty, wet or chip-heavy areas, the 2LS seal is the safer choice because it shields the raceway. The shaft must be ground and hardened to the right tolerance, and the supports need to be aligned so the bearing does not see side loads. Many applications use lifetime lubrication, but harsh environments may call for relubrication.
Cross-referencing is possible with other brands that share the same dimensional and mounting standard, but only if the critical dimensions line up. Check outer diameter, overall length, shaft diameter and seal type before substituting. Do not rely on the part number alone; compare the specifications. If you are unsure, the MR team can review the details with you.

Frequently asked questions
- What does 2LS mean on an SKF LBBR linear bearing?
- It means the bearing has double-lip seals at both ends. These seals help retain lubricant and block contaminants such as dust and chips, which supports longer service in dirty or damp conditions.
- Should I choose a sealed or an open linear bearing?
- Go with the sealed 2LS version when dirt, humidity or particles are present. In a clean, well-lubricated environment, an open bearing may be enough. Also factor in speed and operating temperature.
- Can SKF LBBR linear bearings replace other brands?
- Sometimes, if the critical dimensions match: shaft diameter, outer diameter, length and seal configuration. Never assume compatibility from the part number alone. Verify the specifications or send us your measurements.
