The Bosch Rexroth PLAIN BEARING 4 (R132050400) is a highly functional component designed for various mechanical applications requiring precise plain bearings with flange. This plastic plain bearing, part of the Type R.. series, features an integrated flange that serves a dual purpose. Primarily, the flange acts as a straightforward mechanism to prevent axial displacement of the bearing, ensuring it remains securely positioned during operation. Simultaneously, it's capable of withstanding axially applied forces, adding to the component's versatility and reliability within a system. The design includes a compensation gap and slot that are critical for maintaining the bearing's performance under varying environmental conditions. The compensating gap A along the longitudinal direction of the flange allows for adjustments in size due to changes in moisture levels or temperature fluctuations. This feature not only helps in maintaining dimensional accuracy but also plays a role in conserving lubricant within lubricated bearings and assists in its even distribution throughout the bearing surface. Additionally, radial slots B featured on the flange mirror the functionality of compensating gap A by contributing to dimensional stability and lubrication management. These design elements ensure that the PLAIN BEARING 4 can operate efficiently even when subjected to environmental stresses that might otherwise impact performance. With its robust construction and thoughtful engineering, this Bosch Rexroth plain bearing is suitable for applications where durability and precision are paramount. Its ability to adapt to changing conditions while providing reliable axial support makes it an excellent choice for designers and engineers looking for high-quality components for their mechanical assemblies.
Plastic plain bearings – size 4
Type R13205..00 is a plastic plain bearing with flange. This flange is intended to be a simple holding device against axial displacement. At the same time, however, it can also absorb axially occurring forces

Type R13205..00 is a plastic plain bearing with flange. This flange is intended to be a simple holding device against axial displacement. At the same time, however, it can also absorb axially occurring forces.
Compensation gap and slot
The flange is provided with a compensating gap “A” in the longitudinal direction. This almost compensates for dimensional deviations that occur as a result of moisture absorption or temperature changes, saves lubricant in lubricated bearings, and contributes to its distribution in the bearing. The radial slots “B” in the flange have the same function as compensating gap “A”.

Permissible p ∙ v-values for an ambient temperature of 20°C
From the following diagram, the specific bearing pressures p in N/cm2 can be read for the peripheral speeds depending on the permissible p ∙ v value. For static loading capacity, a specific bearing pressure of p = 1400 N/cm2 is selected.

| The axial load which can be absorbed by the collar must not exceed 25 % of the radial load capacity; for this, shaft collar diameter must correspond to dimension "D" (see dimensions). | |
| The specified values are valid for a bearing temperature ≤ 80 °C and an ambient temperature of 20 °C. |
