Bosch Rexroth R066802500 KBSE-25 25x37x37 mm - Segmental Linear Bushing

Bosch Rexroth R066802500 KBSE-25 25x37x37 mm - Segmental Linear Bushing

Bosch Rexroth R066802500, type designation KBSE-25, is a closed segmental linear bushing designed for linear motion on a 25 mm shaft. The bushing has a 37 mm outside diameter and 37 mm length. It is the standard version without seals, featuring 6 ball rows, hardened load-bearing segments and PA 11 ball guide components.

Technical data

The minimum and maximum load capacity values depend on the direction of the applied load relative to the load-bearing segments.

What does Bosch Rexroth R066802500 mean?

R066802500 is the Bosch Rexroth material number assigned to the specific KBSE-25 segmental linear bushing.

KBSE-25 identifies the bushing size designed for use with a nominal 25 mm shaft.

The product belongs to the Bosch Rexroth family of segmental linear bushings.

The complete material number R066802500 is important for unambiguous product identification. A replacement should not be selected solely according to the 25 mm shaft diameter.

Bosch Rexroth KBSE-25 construction

R066802500 uses a segmental design. The load is transmitted through hardened load-bearing segments working together with bearing steel balls.

The construction includes:

• hardened load-bearing segments

• bearing steel balls

• 6 ball rows

• PA 11 ball cage

• PA 11 retaining rings

• closed bushing design

The segmental construction distinguishes KBSE-25 from other Bosch Rexroth linear bushing families.

R066802500 KBSE-25 dimensions

The principal mounting dimensions are:

d - 25 mm - nominal shaft diameter

D - 37 mm - bushing outside diameter

C - 37 mm - bushing length

The principal dimensions are therefore 25x37x37 mm.

When selecting the bushing, the shaft diameter alone is not sufficient. The housing bore, required radial clearance and method of axial retention must also be considered.

R066802500 load capacity

For the KBSE-25, Bosch Rexroth specifies load capacity values that depend on the direction of the applied load relative to the load-bearing segments.

Dynamic load capacity:

• Cmin: 1630 N

• Cmax: 1730 N

Static load capacity:

• C0min: 1360 N

• C0max: 1750 N

If the direction of load is clearly defined and the bushing can be installed in the most favourable orientation relative to that load, the maximum values can be considered where appropriate.

If the direction of load is not defined or the optimum installation orientation cannot be ensured, the minimum values should be taken into account when evaluating the bearing arrangement.

Version without seals

Bosch Rexroth R066802500 KBSE-25 is supplied without seals.

Separate wiper seals can be used as additional components where required by the linear guide arrangement.

The absence of integrated seals is particularly important when the bushing operates in an environment containing dust, chips, moisture or other contaminants.

Lubrication

This segmental linear bushing requires appropriate lubrication before operation.

Lubrication conditions directly influence friction, wear and service life. The lubricant and relubrication interval should therefore be selected according to the actual operating conditions of the linear guide system.

The requirements of the shaft, housing and complete linear bearing arrangement should also be considered.

R066802500 vs R066802530

R066802500 and R066802530 belong to the same KBSE-25 size family, but they are not identical versions.

R066802500 - standard KBSE-25 version.

R066802530 - KBSE-25-NR corrosion-resistant version.

The two material numbers should not be treated as the same product solely because both are designed around a 25 mm nominal shaft diameter.

How to select Bosch Rexroth R066802500

Before purchasing or replacing this linear bushing, verify:

• material number R066802500

• type designation KBSE-25

• 25 mm shaft diameter

• 37 mm outside diameter

• 37 mm bushing length

• required closed design

• version without integrated seals

• applied load and load direction

• required linear speed

• acceleration

• required radial clearance

• lubrication conditions

• operating temperature

• contamination conditions

• housing design and mounting requirements

A matching 25 mm shaft diameter alone does not confirm complete interchangeability with another linear bushing.

Installation

The bushing, shaft and housing should be clean before installation.

The linear bushing should be installed using a suitable mounting tool and controlled installation force. Damage to the retaining components or load-bearing segments must be avoided.

For housing designs with an opening or slot, the orientation of the load-bearing segments relative to the load direction must be considered.

Correct orientation is technically important because the load capacity of the segmental bushing varies according to the direction of the applied load.

Applications

Bosch Rexroth R066802500 KBSE-25 is a linear motion component designed to operate with a suitable 25 mm linear shaft.

The recirculating ball system enables low-friction linear movement between the bushing and shaft.

Selection for a specific machine should consider load, load direction, speed, acceleration, lubrication, contamination, housing design and required radial clearance.

The R066802500 designation alone does not confirm compatibility with a specific machine, production line or equipment model.
