The Castrol Alpha SP gear oil range of high quality lubricants are based upon highly refined mineral oil, enhanced with an extreme pressure additive technology providing good thermal stability and high load carrying capacity. The extreme pressure additive system not only provides high load carrying capacity, but was designed to provide microscopic wear protection. Microscopic wear protection, also known as micropitting protection, is critical in preventing destructive wear at the micro level therefore extending gear life and meeting the evolving demands of smaller and higher output gear boxes.
Specific grades within the Alpha SP range meet the requirements of:
DIN 51517 Part 3
AGMA 9005 - E02
AIST 224
David Brown S1.53.101 Type E
SIEMENS MD Rev 13 for Flender Gear Units (ISO VG 150 - 680)
Alpha SP is classified as follows: DIN Classification is CLP
Advantages
Extreme Pressure (EP) performance protect gears against wear and shock-loading as measured by FZG
performance and demonstrated extensively in the field.
