LFR5201-10 ZZ INA Double Row Track Roller Bearing for Linear Guide Systems 12x35x15,9

LFR5201-10 ZZ INA Double Row Track Roller Bearing for Linear Guide Systems 12x35x15,9

LFR5201-10 ZZ INA is a double row track roller bearing designed for linear guidance systems and industrial motion assemblies requiring stable movement, high rigidity and resistance to dynamic loads generated during continuous linear operation.

The LFR5201-10 ZZ construction is based on a double row angular contact ball bearing with a gothic arch raceway profile engineered for operation on guide shafts and linear tracks. This type of track roller bearing is used in applications requiring:

• precise linear guidance
• reduced operating clearance
• repeatable positioning accuracy
• stable operation at high travel speeds
• combined radial and axial load capability

The double row ball bearing configuration enables simultaneous support of:

• radial loads
• axial loads in both directions
• dynamic forces generated during acceleration and directional changes

The gothic arch raceway geometry creates two point contact with the guide rail, improving load distribution and increasing guidance stability in automation and linear transport systems.

The ZZ designation indicates:

• metal protective shields on both sides
• reduced contamination ingress
• minimized grease leakage
• suitability for higher operating speed compared with contact sealed versions

ZZ metal shields do not generate direct contact friction against the raceway surface, allowing the roller to maintain low rotational torque and stable operating behavior during high frequency linear motion.

INA LFR series track rollers are commonly installed in:

• linear guide systems
• industrial automation equipment
• CNC machinery
• packaging machines
• transport systems
• positioning units
• handling systems
• linear transfer assemblies

Roller dimensions:

• inner diameter d = 12 mm
• outer diameter D = 35 mm
• width B = 15,9 mm

The phrase LFR5201-10 ZZ INA track roller bearing for linear guide systems 12x35x15,9 is frequently searched in servicing applications involving industrial automation systems, linear motion equipment and precision transport assemblies.

Construction and design

The LFR5201-10 ZZ INA bearing uses a double row angular contact ball bearing construction with a thick outer ring designed for guided rolling motion.
