Bearing Cage Material
Bearing Cage Materail Requirement:
Bearing cage material must have good wear resistance, dimensional stability, good mechanical strength, and perfect adaptation to the operation of the bearing. Therefore, for the selection of cage materials, it is important to consider the operating environment.
Three Common Bearing Cages:
Common bearing cages are as below,
1. Stamped steel cage
2. Brass cage
3. Nylon cage
Stamped Steel Cage:
These lightweight cages have high strength, surface treatment can effectively reduce friction and wear.
The material composition is as follows,
| Steel Code | chemical composition % | ||||||
| JISG 3141 SPCC | carbon | silicon | manganese | phosphorus | sulfur | nickel | chromium |
| < 0.12 | < 0.5 | < 0.04 | < 0.045 | ||||
Brass Cage:
Small and medium-sized bearings use cut brass cages.
But brass cages are not suitable for use in ammonia-cooled compressors, because ammonia causes the brass to crack seasonally, so steel cages should be used instead.
Brass cage chemical composition is as below,
| Standard | Code | chemical composition % | ||||||||
| copper | zinc | manganese | iron | aluminum | tin | nickel | Impurity | |||
| aluminum | silicon | |||||||||
| JIS H 5120 |
CAC301 (HBsC 1) |
55.0 – 60.0 | 33.0 – 42.0 | 0.1 – 1.5 | 0.5 – 1.5 | 0.5 -1.5 | < 1.0 | < 1.0 | < 0.4 | < 1.0 |
| JIS H 3250 |
C 6782 | 56.0 – 60.5 | 0.1 – 1.5 | 0.5 -1.5 | 0.5 -1.5 | – | – | < 0.5 | – | |
Nylon Cage:
According to the types and uses of bearings, nylon cages are used more and more widely.
However, nylon retainers are not suitable for use in environments over +120°C or below -40°C.
Most cast-molded cages use nylon PA66, which may be reinforced with or without glass fiber, and is characterized by a good combination of strength and elasticity.
The life of the nylon cage decreases with the increase in temperature and the aggressiveness of the lubricant.
Therefore, whether the nylon cage is suitable for a specific purpose depends on the operating conditions and the requirements of the life.

Questions that help before the next bearing decision after Bearing Cage Material
Which next options usually help after reviewing Bearing Cage Material?
Most buyers benefit from one broader family destination, one more commercial route, and one supporting guide that answers the next practical question. That combination usually turns research into a clearer shortlist.
Why add related bearing destinations beside Bearing Cage Material?
Because the first answer often leads to a second question about fit, applications, supplier choice, or repeat-order confidence. Keeping those next destinations close reduces unnecessary backtracking.
When is it worth moving from reading into a quote or product review?
That move usually makes sense once the topic has narrowed the likely bearing family and the remaining unknowns are commercial, dimensional, or application-specific rather than purely educational.
What usually makes the next bearing decision easier after Bearing Cage Material?
The process is often easier when the wider family view, the more commercial destination, and one practical guide stay visible together. That keeps the decision grounded in both application detail and buying reality.
Buyer FAQ
Questions buyers ask before choosing the next bearing option
What is the main takeaway from Bearing Cage Material?
The main takeaway is that bearing cage material should be checked against the bearing family, dimensions, load direction, speed, and operating conditions instead of relying on the title or size alone.
When should I use this guide before requesting a quote?
Use the guide when you are comparing bearing models, checking suffix meanings, confirming seal or clearance choices, planning maintenance, or preparing details for replacement, production, or OEM sourcing.
How does this topic connect to bearing supply?
The topic supports the Bearing Supply decision path by helping buyers understand fit, performance, specification details, or maintenance factors before choosing a product page or contacting the team.
Can this guide replace a final specification check?
No. The guide helps prepare the decision, but a final check should still confirm the part number, dimensions, load, speed, seal, clearance, precision, application, and order quantity.
What should I send if I need help after reading this guide?
Send the bearing number, measured size, photos if available, application, quantity, and any special operating conditions. That gives the team enough context to recommend the right product family or quote route.
