What type of gear oil does a hard-to-penetrate brake use

　　Hard-toe brakeTeether oil no. 220 (l-ckd heavy load type) is usually selected, with the specific type adjusted for ambient temperature, load strength and equipment condition。
Core selection basis
1, viscosity level adaptation
Temperature environment (0-30°c): priority is given to iso vg 220 carbs, which have viscosity characteristics that meet the need for a hard-to-penetrating machine to lubricate under conventional loads。
High temperature/reloading (30-45°c): it is proposed to upgrade to vg 320 carbs to increase the intensity of the oil membranes, such as mines, metallurgy, etc。
Temperature environment (below -10°c): vg 150 or low temperature mobile multi-stage gear oil (e. G. 85w/90)。
2. Performance level requirements
Hard-teeth-reducing machines with high exposure stress (usually > 1100 mpa) are selected with l-ckd heavy loads of very low-pressure wheel oil, which contain an additive of parathion that is effective in preventing injury and wear to the teeth。
Operation and maintenance recommendations
Oil exchange norms:
The gear oil will need to be replaced after 100 to 200 hours of initial operation, followed by replacement every 5,000 hours or 12 months。
Before oil is replaced, ensure that the equipment is operating at the temperature and that old oil is drained。
Special case adjustment
If the equipment is frequently suspended or subject to an impact load, enhanced gear oil with an anti-repeated agent, a sealed regulator, such as cardido syntilo 320 or kunlón 320, may be used。
