1 Can plasticpolymer bearing handle a significant radial loa

1. Can plastic/polymer bearing handle a significant radial load/force on the shaft it supports? What about an axial load/force? Of the two, which can the bearing tolerate better?

2. Identify any issues with this particular bearing which may cause noise, vibration, or unwanted motion in the supported shaft.

Solution

Plastic bearings can handle radial loads easily . They are made in form off plain bearing.

they can also support thrust load at modearte level.

Car tires, for example, carry a radial load when driving in a straight line: the tires roll forward in a rotational manner as a result of tension and the weight they are supporting. However, when a car goes around a corner, it is subject to thrust load because the tires are no longer moving solely in a radial fashion and cornering force weighs on the side of the bearing.

But with plastic bearings these issues can happen

. Lower static capacity

More heat buildup

Lower tightening torque than metal parts (from thread)

Inability to directly fix the ball with a screw (a metal sleeve is required)
