One thing I suggest you do is get the OEM lubricant recommendations for a few machines using the Chevron SR1#2 and see what others brands might be listed. Rarely does a machinery manufacturer list a single lubricant to the exclusion of others. Otherwise, I think its time for you to put Google to work. A simple search using "chevron sr1 2 equivalent" yield somes hits, one of which is an equivalency chart by Timken Bearing Company.

Are you intending to mix grease types? If so, you should also consider compatibility among the greases (alternative doesn't necessarily mean compatible to me).

if you are looking for alternative check the technical data of chevron you will find the base oil and thickener and so on, then you can find the alternative using this data.

the grease you mention seems to be based on a polyurea type of thickener. those greases are known for their wide temperature operating range and long useful life under high temperatures. their composition is quite different from the more standard lithium based greases that are widely used.

no doubt other grease manufacturers will be able to supply a comparable type of grease that could do the job just as well. but mixing these types of grease may lead to problems and is better avoided.

if you want to use a alternative grease you best contact your lubricant supplier which product to use and how to change over to the alternative. their advice might well be to dismantle and clean the bearings completely and then fill them with the right amount of the new grease (usually somewhat less then you would be inclined to, more bearings fail from excess lubrication then from to little grease....).
