When replacing or removing an antifriction ball bearing, the applied force should:

Oil grooves in a sleeve bearing distribute oil:

The property of an oil which indicates its ability to support a load is:

The lubricant for an anti-friction bearing:

The point at which oil will give off enough vapour to ignite and burn continuously, is known as:

What problem can arise from adding too much grease to a bearing?

Why is Babbitt such a good metal to use in shell bearings?

A turbine oil should not:

A disadvantage of sodium based greases is:

Why aren't oil grooves located in the pressure zone of a shell bearing?

An oil with a low viscosity index:

The lowest temperature at which an oil will flow is known as the:

The white metal which is normally used in shell bearings is called:

This class of liquid lubricant is suitable for high temperatures and is resistant to sludge formation and oxidation:

Boundary lubrication is characterized by:

When starting-up a rotary pump you must be sure that the:

By cooling the air between stages the power required for compression is:

When a reciprocating pump discharges while its piston or plunger moves in only one direction, it is termed a:
