The SKF LBBR series linear bearing is a guidance component that allows smooth and precise axial movement on cylindrical shafts. It is used in applications requiring linear motion with low friction, such as machine tools, automation equipment and transport systems. MR Accesorios Industriales supplies this SKF line, an official brand it represents, to provide reliable solutions in power transmission and motion.
The LBBR series designation is interpreted as follows: the letters LB indicate that it is a linear ball bearing, the second B refers to its compact design and the R to the fact that it has a ball retention cage. The number that follows, as in the examples LBBR 16, LBBR 40 or LBBR 50, indicates the nominal shaft diameter in millimeters that the bearing can accommodate. Thus, an LBBR 16 is designed for a 16 mm shaft, an LBBR 40 for a 40 mm one and an LBBR 50 for a 50 mm one. This nomenclature allows you to quickly identify the size needed for each application.
These linear bearings are used in a wide variety of industries in Argentina. They are common in CNC machines, measuring equipment, robotic arms, pick and place systems, and in general in any mechanism requiring repetitive, high-precision linear motion. They are also found in the food, automotive and medical device manufacturing industries. Their ability to withstand radial loads and moderate moments makes them versatile for linear guide design.
When selecting an LBBR linear bearing, it is essential to verify the shaft diameter and housing tolerance. Assembly must be carried out with careful alignment to avoid lateral loads that reduce service life. Proper lubrication, generally with low-viscosity grease, is essential to minimize wear. In addition, sealing must be considered: if the environment contains dust or particles, versions with integrated seals should be chosen. Internal clearance and preload also influence the precision and rigidity of the system.
Regarding equivalences and interchangeability, SKF LBBR series linear bearings can be replaced by products from other manufacturers that follow the same dimensional designation. However, it is important to verify tolerances and load capacity, as they may vary between brands. Part numbers from other brands must not be invented; it is always advisable to consult a specialist to ensure compatibility. MR Accesorios Industriales can advise you on selecting the right alternative for your application.

Frequently Asked Questions
- What does the number in the LBBR 16 designation mean?
- The number 16 indicates the nominal shaft diameter in millimeters that the bearing can accommodate. In this case, it is designed for a 16 mm shaft. Suffixes may indicate variations in sealing or cage, so it is advisable to verify the complete data sheet.
- What is the difference between a linear bearing and a bronze bushing?
- The linear bearing uses recirculating balls to reduce friction and allow smooth, precise movements at high speeds. The bronze bushing, on the other hand, works by sliding and is usually more economical but with higher friction and lower precision. The choice depends on the application.
- How are SKF LBBR linear bearings lubricated?
- They are lubricated with low-viscosity grease or oil. The frequency depends on the working conditions: in clean environments and at moderate speeds, the initial lubrication can last a long time. In demanding applications, a regular maintenance program is recommended.
