Pressed Steel Cage 29400 Series Thrust Spherical Roller Bearings

Pressed Steel Cage 29400 Series Thrust Spherical Roller Bearings: The standard cage of volume bearing production: light, cheap, tolerant of temperature and unaffected by the oils that age a polymer cage. The material decides the corrosion behavior — as the rings — it relies on the lubricant and the seals and the temperature the part will stand (not the limiting element; the lubricant and the ring heat stabilization decide), and it is the reason the alternatives below exist. Properties, limits and the full size table follow.

Why Pressed Steel Cage for 29400 Series Thrust Spherical Roller Bearings

The standard cage of volume bearing production: light, cheap, tolerant of temperature and unaffected by the oils that age a polymer cage. In a 29400 series thrust spherical roller bearings it is the cage, which spaces the rolling elements and keeps them from touching each other.

Pressed from sheet and guided by the rolling elements, it adds almost no mass and almost no cost, tolerates a wide temperature range, and is unaffected by lubricant chemistry. It is the default cage of the standard bearing ranges for good reasons.

Material Properties

Service Limits

It is a light-duty cage: it is guided by the rolling elements and it is not intended for heavy vibration, high acceleration or sustained very high speed, which is where the machined brass cage takes over. In a heavily shocked application, cage damage rather than raceway fatigue is what ends the bearing.

Alternatives and When to Switch

Polyamide where quiet running and low friction matter and the temperature is moderate; machined brass where speed, shock or lubricant chemistry rules both of the others out.
