Standards
Cylindrical roller bearings, single row: DIN 5412, part 1
Cylindrical roller bearings, double row: DIN 5412, part 4

Tolerances, bearing clearance
Bearing clearance is distinguished between radial and axial. Design versions like NUP or NJ + HJ need also attention in axial next to radial clearance. Tolerances are in accordance with ISO 492 and clearance is in accordance with ISO 5753.

Cages
All the cylindrical roller bearings of the series NU10, NU18, NU19, NU2, NU20, NU22, NU23, NU28 NU29, NU3, NU30, NU31, NU4, NU60, NN30.., NN48, NNU48, NNU49 and NNU60 are preferably delivered with machined brass cage.

The following machined cages are available:

  • Chamber-type cages, letter code M
  • Window-type cages, letter code MP
  • Comb-type cup cages, hot-riveted steel rivets, letter code M2
  • Comb-type cup cages, spider riveted, letter code M3
  • Comb-type cup cages, bolted, letter code M4 (available only for bore diameter 64 and higher)


The following types of machined cage guidance are offered for cylindrical roller bearings:

  • Roller guidance, no extra letter code
  • Outer roller guidance, additional letter code A
  • Inner roller guidance, additional letter code B


Angular adjustment
The modified line contact between rollers and races of cylindrical roller bearings avoids edge tension, and allows a slight adjustment of the contact angle. The adjusted contact angle shall not exceed four minutes with a load ratio

NU10/750 W33 Chamber Cages Steel Ball Bearings , Machine Tool Bearings With Rough Ground Inner Ring

of single row cylindrical roller bearings (P = equivalent dynamic load [kN], C = dynamic capacity [kN]). The mounting positions of double row cylindrical roller bearings shall be free of any misalignment.

Design versions of cylindrical roller bearings
There are not only the standard types NU and NJ

The following combination specifications are common:
for NU + HJ: NUJ
for NJ + HJ: NH
for WU + HJ: WU..W

The bearing versions NU or NNU are used as examples of technical specifications such as load ratings and speed limits.

Cylindrical roller bearings are also available with a rough-ground inner ring raceway. You can also order bearings without an innerring (RNU) or without an outer ring (RN).

Equivalent dynamic load
The following applies to a cylindrical roller bearing with radial load:

P = Fr [kN]

If the radial force is combined with an axial force Fa, it will be considered in the bearing service life calculation, where Fa Fa zul admissible must be (Faadmissible = admissible axial force).

Admissible axial load
Cylindrical roller bearings of the series NUP, NJ, NJ with angular rings (NH) and cageless bearings of the series NJ..VH, NCF..V and NNF..V may accept axial forces, if they are also loaded in radial direction. The maximum axial load admissible is

NU10/750 W33 Chamber Cages Steel Ball Bearings , Machine Tool Bearings With Rough Ground Inner Ring

if

NU10/750 W33 Chamber Cages Steel Ball Bearings , Machine Tool Bearings With Rough Ground Inner Ring

is ensured.

It depends on:

  • radial load
  • speed
  • lubrication
  • operating temperature and heat transfer conditions

The theoretical axial load is determined calculating the heat balance at the bearing positions, and may be estimated as follows:
