Cylindrical roller bearings are available in a wide range of designs, series, variants and sizes. The main design differences are the number of roller rows and the inner/outer ring flanges as well as cage designs and materials.

 

Cylindrical Roller Bearings also have many different design as follows

--Single Row Cylindrical Roller Bearings

--Double Row Cylindrical Roller Bearings

--High Capacity Cylindrical Roller Bearings

--Single Row Full Complement Cylindrical Roller Bearings

--Double Row Full Complement Cylindrical Roller Bearings

 

Single row cylindrical roller bearings have NU, NJ, NUP, N, RNU type, as well as the complete single row cylindrical roller bearings, cylindrical roller bearing without outer ring etc. Cylindrical roller bearings are also available in sealed or split designs. In sealed bearings, the rollers are protected from contaminants, water and dust, while providing lubricant retention and contaminant exclusion. This provides lower friction and longer service life. Split bearings are intended primarily for bearing arrangements which are difficult to access, such as crank shafts, where they simplify maintenance and replacements. 

 

And different types of cylindrical roller bearings also have their different design according to their feather, and also many kinds of cages, just like Brass cage, Pressed Steel cage, nylon cage etc.

The bearings can meet the challenges of applications faced with heavy radial loads and high speeds. Accommodating axial displacement (except for bearings with flanges on both the inner and outer rings), they offer high stiffness, low friction and long service life. 

 

NUPK310 NR Cylindrical roller bearings with up to three times longer service life than the previous EASIER standard, which is superior to all other conventional cylindrical roller bearings. The performance improvements of EASIER cylindrical roller bearings over the past 15 years have permitted downsizing, whilst still maintaining the required performance

 

Material

EASIER bearings feature an extremely clean and homogenous steel with a minimum number of inclusions. This improved steel is so much cleaner than the highest grades covered by present classifications. The reduction in the number of inclusions increases the fatigue strength in the rolling contacts and enables the bearings to operate much longer.

 

Heat treatment

New heat treatment procedures optimize the bearing resistance to operational damage and temperatures without affecting dimensional stability.

 

Logarithmic contact profile

This important feature of EASIER cylindrical roller bearings – for the past years – has been further refined for the rollers used in EASIER bearings. The bearings are thus even less sensitive to small misalignment and can carry heavy loads.

 

Roller end/flange geometry

The optimized roller end/flange contacts of EASIER cylindrical roller bearings are also present in EASIER bearings. The resultant advantages include reduced friction, lower operating temperatures and less wear

 

Material hardness

The hardness of the rings and rollers of EASIER bearings have been selected for optimum performance. This makes them less sensitive to contaminants and contributes to their extremely long service life.

 

Surface finish

The surface finish of the raceways on the rings and rollers has been further refined and provides enhanced lubrication conditions in EASIER bearings so that they can operate longer even under poor lubrication conditions.

 

Manufacturing quality

Upgraded manufacturing processes have contributed to a significant improvement in product quality. This means that the rings can be produced with an increased roundness and the deviation from true form of the rollers has also been further reduced. The results of the tighter tolerances may be invisible but the bearings run markedly quieter and with less vibration.

 

Cage design

The design and material of the cage can have a significant impact on a bearing’s ability to withstand given operating conditions. That is the reason for making bearings available with up to four different cages. The design of the cages used in EASIER bearings contributes to good lubrication of all contact surfaces, even under occasional interruptions in lubricant supply.
