To become Premier, the standard bearings must meet strict requirements in 4 fields which determine their reliability and their life :
|
| |
|
| |
|
A thorough control of steel: less wear, less damage, more
stability at high temperature.
Bearing finish: reaching levels of regularity seldom obtained,
Design optimization: reaching far greater load capacity
Sealing and lubrication: operation at higher speeds, and
increased durability.

| SNR Premier Spherical Roller Bearings |
| |
| As first beneficiaries of the Premier technology, the SNR spherical roller bearings achieve an 18% load capacity increase and a service life extension of at least 75% . Further improvements are: |
| |
Reduced friction torque, as much as 30% less, offering lower operating temperature,
with lower power and lubricant consumption.
Increased operating speed allowing an extended scope of applications.
High temperature capacity up to 200oC for metallic cage bearings, with ensured
dimensional stability due to specific heat treatment.
Mis-alignment capability increased by 0.5o without reducing the load capacity,
and up to 1o 30' in case of low loads.

| SNR LubSolid |
| |
|
LubSolid is a porous polymer material containing a large quantity of oil. This matrix completely fills the free volume in the bearing, providing 3 to 4 times more oil than with conventional grease. For a speed factor N.Dm=100.000, SNR proposes this new concept LubSolid.
LubSolid advantages:
Extended service life
No relubrication required.
Enviromentally friendly.
Better seal
