bearings

1. Appearance characteristics：
Roller diameter increase, rolling body length increase
Maintains a raised edge guide roller from invading.this, and to reduce roller reaction
Adopt inner circle, improve roller raised edge guide roller operation
Cylindrical roller bearing keep wearing USES integral structure, strength greatly increased
Self-aligning bearing outside diameter design have oil, lubricating oil hole effect is good.
2. Optional materials:
Internal and external circle and roller adopts vacuum deairing with bearing steel, fatigue durable good performance
Keep wearing USES aluminium, fe and mn bronze materials, high strength, good flexibility, wear-resisting performance is better
3. Heat treatment
By beth - horse inside circle markov quenching temperature quenching or mixed uniform hardnessespecially stress, tempering small; Good toughness and impact and vibration
resistance.
When the temperature 150C within the work, the stability is good
4. Tolerance and manufacturing
Strictly according to standard manufacture precision at the level of tolerance degrees, especially in diameter is very small
Scroll body size mutual sent acuities 0.002
Cylindrical roller diameter, avoid a convex degrees of stress concentration practice.
Scroll surface super-fine processing, high polished.
5. Internal clearance
Clearance press vibration machine requires production, within the scope of control in a very small range, good consistency
6. Using effects
Low noise, small temperature, better stability and long service life, no early fatigue phenomenon.
