Description

Product description

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.
