As a result of the TIMKEN bearing tapered roller bearing cage is generally not under load, only around the raceway on the role of the separating roller, so most TIMKEN bearing retainers are made of low carbon steel to suppress.
Non-ferrous metal processing of the cage
Some TIMKEN bearing using this type of cage.
Special reinforcement cage
Some special purpose, such as the need for high power and high speed, heavy load swing and the axial vibration and/or high acceleration and deceleration, etc., you must choose special reinforcement cage.
These special "L -" type cage is made of thicker material, the distance between each other is bigger also, therefore, compared with a standard bearing design, roller using fewer). Because of the design of this kind of cage cage is oriented to the small guard outside diameter of inner ring.
Pin type cage (pillar type cage)
Pin type cage is composed of two ring, roller ends of each one. Keep the frame pillar holes through the center of each roller, lock in a ring, and with another ring welding. When designing use pin type cage, medium and large aperture TS can have more of a roller bearing, thus can improve the bearing capacity.
Polymer cage
Some of the design for special use this bearing, such as UNIPAC cage bearing using the polymerization. Other special bearings, such as cross roller bearing, using the polymerization between roller separation piece, rather than a company as one of the cage.
According to the standard ISO metric tapered roller bearings, NACHI Bearings Dimensions its model is according to the following principles:
ISO 355:1977 standard, bearing series code includes three strings, the first digit represents the contact Angle, the second and third letters on behalf of the diameter and the width of the series, followed by three Numbers to indicate the bearing inner diameter d (mm). SKF before the entire model coupled with a prefix T, such as T2ED 045.
Model of the development of the before 1997, in line with the "bearing code", such as 32206.
Metric SKF bearing with prefix J meet ABMA code system, with its imperial bearing similar code system. For more information, see the ANSI/ABMA 19.2-1994 standard.
Imperial bearing type imperial SKF tapered roller bearing used code system in line with the ANSI/ABMA.
Metric bearing with series of SKF bearing, regardless of any size, have the same proportion of cross section. But it is not like that inch bearing. Gm series of imperial SKF bearing, roller and cage components, using the same but have different inside and outside the ring size and design.
The same series of imperial bearings, inner ring components can be used with any outer ring. So the inner ring components and outer respectively has its independent models, can purchase alone, also, you can purchase a complete set of bearing. Inner ring components with outer ring and its series of code is composed of 3 to 6 Numbers, and letters, such as EL, LL, M, L, LM , HM, H, HH and EH for prefix. Prefix representative from very light to very heavy series of bearings. The basic principles of the code system in ANSI/ABMA19.2-1994 in detail.
A complete set of bearing model is made up of inner ring component model combined with the outer ring model, separated by a slash its between two models.
In order to avoid the whole model is too long, the new code system in the form of abbreviations to simplify it.
