Radial Spherical Roller Bearings in X-life Quality

X-life Design

20.05.2020 Product Management SRB - PJ/SWE-CS 4

Spherical roller bearings in X-life design meet the requirementsof DIN 635-2 and can replace the E spherical roller bearingdesign.

▪ New bearing design with increased performance

▪ New roller dimensions with crowned side-face

▪ Movable central rib

▪ Improved surface quality

▪ Upgraded running accuracy

▪ Improved contact geometry between rollers and

raceways (rollers with additional profiling)

▪ Reduced bearing friction

▪ New cages in steel and brass

Product Range

20.05.2020 Product Management SRB - PJ/SWE-CS 5

X-life design:

▪ DIN635-2

▪ 8 series

▪ cylindrical or tapered bore

▪ with OD from 52 to 650 mm

▪ consequent conversion of large size bearings to X-life design

▪ majority of types with OD ≤ 920 mm already converted to X-life (see X-life roll-out plan)

Cage Design for X-life SRB with OD larger 320 mm

20.05.2020 Product Management SRB - PJ/SWE-CS 6

1) - If some customer need brass cage version, you have to start an an RFQ-process/workflow with BEA-XL-MB1 version- Steel cage, inner ring guided, is not part of the designation

2) - Except serie 241..up to OD ≤ 720 mm (up to 24188-BE-XL) with steel cage, inner ring guided- Machined brass cage -MB1 is part of designation

non-profiled area

Further details

Descripiton

▪ Roller radius is optimized by a superposed logarithmic profile

Effect:

▪ Superior wear resistance esp. at harsh conditions

▪ Optimized overload protection (lower risk of edge pressures)

Customer benefits:

▪ Increased operational reliability

▪ Increased machine availability
