ENGEERING INFORMATION
MATERIALS
RINGS&BALLS-XLD uses home made or imported vacuum degrassed.high carbon,chromium bearing steel as it is standard material for precision bearing rings and balls.
RETAINERS-XLD standard bearing retainers are made from quality cold rolled carbon steel. Nylon or brasses are available upon request.
SEALSS&SHIELDS-XLD shields also employ quality carbon steel as standard. LD uses a variety of high temperature operation and compatibility with grease.Buna-Nitrile is the
standard material used.
LUBRICATNTS-XLD are chevron and Alvania#2 used in our factory.
2. Tolerance
Bearing tolerance includes dimensional tolerance and revolving tolerance. dimensional tolerance is a request when bearings are mounted on shafts or in housings. it includes bore /outer side diameter deviation from basic.innerring /outer ring width deviation from basic and radius allowance. Geometric tolerance includes bore/outside diameter deviation in single planne,innerring /outerring width deviation in single radial plane. revolving tolerance includes radial and axial run out of assembled bearing innerring and outerring,innerring referring reference face run out with bore and outside cylindrical surface run out with outerring reference face.
Tolerance class ranges from common class 0to 6 5 4 and 2, from low to high,tolerance class as below text.

3 Clearance
Bearing clearance means the value of displacement of the unfixed ring when it moves against the fixed ring in radial or axial direction before the bearing in mounted on a shaft or in a housing, according to movement direction it falls into radial clearance and axial clearance.
The standard clearance for XLD deep groove ball bearings are dividing into four groups,C2 C0 C3 C4 as show below.

4.Vibration
Bearing vibration means bearing components elastic information that varies with time and all other movement that deviates from a theoretic position except that necessary to bearing functions, it has two modes-acceleration(db0and velocity (UM/s),vibrarion acceleration level rangesfrom low to high.similary,vibration velocity is examined as per V V1 V2&V3grade V is fundamental V1 V2 V3 successively indicate the vibration level from low to high..generally,Velocity examination is better than acceleration examination in that it can more reflect bearings manufacturing level and bearings inherent quality.
While our company keeps control of vibration velocity values, we also carry out vigorous control on abnormal noise from running bearings in test according to requirements of electric motor quality bearings
1.Spherical insert ball bearing SA206
The features of spherical insert ball bearings
The internal structure of the insert ball bearing is the same with that of deep groove ball bearing. But the inner race of this bearing is wider than the outer race. The outer race has the spherical surface. Insert ball bearings can self aligning with the fit between the outer race and the bearing block. Insert ball bearings are compact. It’s easy for loading and unloading. Spherical insert ball bearings often used in mining, metallurgy, textile, transportation machinery, etc.
