Single row cylindrical roller bearings

• N, NJ, NU, and NUP
• also available as full complement or double row bearings
• high radial loads
• accurate radial guidance due to a narrow radial clearance

Single row angular contact ball bearings

• are used primarily as thrust bearings, mounted singly or in tandem (in a tandem arrangement, they can accommodate high thrust loads)
• suitable for radial loads and high thrust loads in one direction
• also available with an FP cage for pumps used to pump ammonia (pumps)
• type “B“ with a 40° contact angle can accommodate higher thrust loads (pumps)
• also available with seals
• newly developed pressed cages with an optimized cage geometry

Double row angular contact ball bearings

• are used primarily as thrust bearings, mounted singly or in tandem (in a tandem arrangement, they can accommodate high thrust loads).
• suitable for radial loads and high thrust loads in one direction
• also available with an FP cage for pumps used to pump ammonia
• type “B“ with a 40° contact angle can accommodate higher thrust loads
• also available with seals
• newly developed pressed cages with an optimized cage geometry

Spherical roller bearings

• are used in pumps that are subjected to great stress, involving increased shaft deflections and misalignments
• can accommodate radial and thrust loads at the same time
• suitable for very high loads
• self-aligning (up to 2°)
• are dimensionally stabilized up to an operating temperature of 200°C

Tapered roller bearings

• high thrust and radial loads
• accurate radial guidance due to a narrow axial clearance

Deep groove ball bearings

• are used primarily as floating bearings, less frequently as locating bearings
• suitable for high speeds
• also available with seals
• grease-lubricated deep groove ball bearings are suitable for high n x dm values
• depending on the specific application, for-life lubrication is possible, i.e. no relubrication is required

Four point bearings

• are used in compressors primarily as thrust bearings, no accommodation of radial loads
• can accommodate high thrust loads in both directions as well as low radial loads
• thanks to their split inner ring, they incorporate a large complement of balls, resulting in a higher load carrying capacity
• thanks to their split inner ring: a machined cage makes them suitable for high speeds
• accurate axial guidance due to a narrow axial clearance
• compact bearings – no separate retainer bearing required
