BEARINGS WITH SOLID LUBRICATION

BEARINGS WITH SOLID LUBRICATION

Bearings with solid lubrication are manufactured under the NTN brand (SolidGrease) and the SNR brand (LubSolid). They require a special grease, solidified after injection in the bearings, which can retain a greater quantity of oil than standard grease, as necessary for the lubrication of the bearing during operation.

• No service
- Reduced, or even zero, servicing
- Less servicing for inaccessible bearings

• Resistance to contamination
- High performances in dusty and/or humid environments
- The use of sealed bearings is recommended for applications with high levels of contamination. This type of lubrication can be used to improve bearing sealing

• No grease leaks
- No grease leaks and low oil leakage: guaranteed clean operation

• Excellent resistance to centrifugal forces, vibrations and low-scale oscillations
Lubricant in the form of a solid mass, ensuring:
- excellent resistance to centrifugal forces
- the amount of oil necessary for satisfactory operation

• Low start-up torque
“SPOT PACK” type bearings: very low start-up torque at ambient temperature

• Pulling or transfer pulleys

BEARINGS WITH INTEGRATED SENSORS

Integration of a speed and/or position measuring function, in the bearing function.
Basis bearing: LU sealed version (unilateral), greased. A magnetic encoder is fitted opposite the seal on the inner ring, with a sensor on the outer ring. The sensor detects the magnetic variations induced by the rotation of the encoder. The sensor then emits an output signal, enabling the electronics to recalculate the speed of rotation. By modifying the type of magnetic encoder, it is also possible to measure angular position.

Range: 6202 to 6210
Service temperature: from -40° to +120 °C

RADIAL AND AXIAL PLAIN BEARINGS

The range includes plain bearings steel / steel (lubrication required) and in steel / self-lubricating (PTFE + inner ring with hard chromium plating):

Steel/steel

SA1 Equivalent to ISO “E” series
SA1 ..SS Identical to SA1, but with seals
SA2 Inch plain bearing
SA4 Increased dimensions
SAT Axial plain bearings
Steel/self-lubricating
Series Definition
SAR1 Equivalent to ISO “E” series

INDUSTRIAL CONSTANT VELOCITY JOINT

The range includes entirely constant velocity joints, even for large angles, with the following characteristics:
• 3-ball joints (TBJ)
- Standard catalogue components
- Sealed with life-long greasing
- Flange or direct shaft assembly
- Single or double-effect
- Drive torque: from 3.2 to 1500 kgf.m
• 6-ball joints (BJ)
- High power constant velocity joints
- Supplied with fixed or sliding shafts
- Open or sealed
- Drive torque: from 155 to 6440 kgf.m


Applications: machine tools, glasswork, industrial washing machines, agricultural machines, industrial packing machines, vibrating platforms, steel and metal industry, crushers, screeners, etc.

TENSION LEVELLER

Complete assemblies equipped with low-torque bearings and with a ground outer diameter. CU type leveller cylinders can be used to absorb radial and axial loads thanks to angular contact ball bearings, while maintaining high rotational precision and compatibility with high speeds.

  • Equipped with baffle-type low-torque seals
  • For higher loads, these components can be equipped with needle bearings (type NKZ) enabling an increase in load capacity for the entire assembly while maintaining very high rotational precision and a compact format

Cylinder lengths are adapted to each application based on a standard range of defined diameters.

SPLIT BEARING

For some applications, it is not possible to fit traditional bearings, split bearings must be used.
Mounting, dismounting and maintenance are all simplified
Possible variants:

  • Cylindrical roller bearings
  • Spherical roller bearings
  • Needle cages, needle bearings
  • Complete bearing units equipped with cylindrical roller bearings with no cage for steel and iron units (continuous casting)
