USSR STANDARD FOR BEARING LUBRICANT (GOST 1631-42)
1. This standard applies to consistent lubricant (for ball and roller
bearings operating at a working temperature up to 1100 C) prepared by thicken-
ing rcIined petroleum lubricating oils with sodium and calcium salts of castor-
oil fatty acids.
2. The lubricant is a homogeneous oily paste, light yellow to dark brown
in color. Vhen spread in 8 thin film, it appears clear, with a smooth, non-
fibrous structure.
Physicochemical Properties Values Test Method
1. Penetration (Richardson)
at 250 C (without pre-
liminary stirring)
2. Drop-point temperature
(Ubbelohde), not lower
than
3. Water content, not more 0.75%
than
4. Free alkali, in terms of 0.2%
NaOR, not greater than

NOTE: I. Bearing lubricant with a higher penetration number is permitted upon
specification by the consumer.
ii. Specifications as to soap content (see 10), viscosity of mineral oil
entering into the lubricant (see 11), and freezing point of this oil
(see 12) are not tested and are not guaranteed by the plant manufac-
turing the lubricant.
4. For testing thermal stability, take a sieve with 6,400 holes per square
centimeter (200 mesh), and make in it a cup-shaped depression corresponding in
inside diameter to a beaker of 50 milliliters, capacity. Cover the beaker with
the sieve. In the hollow of the sieve place 10 g of lubricant, weighed accurate
to 0.1 g and put both beaker and sieve into a thermostat heated to 1101- 10 C
for 2 hr.
The lubricant is considered to have passed the test if in the course of
2 hr no oil has seeped from sieve to beaker.
5. The test for chemical stability is performed in a tin box 50 x 100
millimeters in size and about 100 millimeters high in which the lubricant to be.
tested is. smeared, and carefully smoothed out with a spatula. The box with the
grease is placed in a thermostat heated up to 100 f 30 C for 72 hr. A second
box, packed by the same method and tightly covered with a well-fitting ?id, is
placed for 72. hr in a dark place with a temperature of 20-25? C. At the end* of
the fixed pe?iod of the test, both boxes are illuminated and the lubricant sam-
ples in them are compared.
The sample of lubricant subjected to heating is considered to have
passed the test if its surface has not developed an observable skin and coating
and if it has become only slightly dark in comparison with the second sample.
