The specification table lists, for each grade, kinematic viscosity at 40 °C and 100 °C, viscosity index, pour point, flash point and four-ball weld load, each with its test method. Share operating conditions with our technical team to confirm the grade before supply.
Application
Spur, helical and bevel gear units where the manufacturer specifies an EP gear oil in one of the ISO VG grades offered.
Feature
ISO VG 68: KV40 69 cSt, KV100 8.7 cSt, VI 102, pour point -21 °C; ISO VG 100: KV40 99 cSt, KV100 10.6 cSt, VI 101, pour point -18 °C; ISO VG 150: KV40 151 cSt, KV100 14.9 cSt, VI 99, pour point -15 °C; ISO VG 220: KV40 224 cSt, KV100 17.8 cSt, VI 98, pour point -15 °C; ISO VG 320: KV40 321 cSt, KV100 23.6 cSt, VI 96, pour point -12 °C; ISO VG 460: KV40 465 cSt, KV100 31.5 cSt, VI 96, pour point -12 °C; ISO VG 680: KV40 684 cSt, KV100 42.5 cSt, VI 95, pour point -12 °C; ISO VG 1000: KV40 1030 cSt, KV100 55.5 cSt, VI 97, pour point -9 °C.
Feature
Published kinematic viscosity at 40 °C sits inside the ISO 3448 tolerance (mid-point ±10 %) for ISO VG 68 (69 cSt); ISO VG 100 (99 cSt); ISO VG 150 (151 cSt); ISO VG 220 (224 cSt); ISO VG 320 (321 cSt); ISO VG 460 (465 cSt); ISO VG 680 (684 cSt); ISO VG 1000 (1030 cSt).
Feature
Besides viscosity, the published data includes four-ball weld load, flash point (COC) and foaming tendency.
Start from the equipment manufacturer's viscosity recommendation at operating temperature. The ISO VG number is the mid-point kinematic viscosity at 40 °C (ISO 3448), and each grade's published values are listed separately.
Next step
The range above is what we publish. Formulation to a customer brief is a route of its own, and a sample is the first stage of it.
