what is this? Oiler or grease ******?

[tvruwink]

Hello -
I've got an old 20" Crescent Heavy bandsaw. I've got it wired up with a VFD and it's running. I'm still figuring out tuning the bandsaw, blade tension etc.

But, I've got a few of this grease or oil ports - see pic. I think this bandsaw is from the 40's. I've never seen anything like these. What tool do I need to oil and/or grease the bearings? Are these considered zercher ports? Sorry for my lack of knowledge. I haven't done anything with them - the wheels turn easily, and I don't feel any grinding etc.

Thanks.

No image shown, most common are Zerk fitting, but there are also Button fittings and flush fittings to name a few.

This doesn't mention zerk fitting. Is yours newer, retrofitted, etc?

I'd poke around here to find the correct manual if that one isn't for yours.

There are other fittings, little cup-like thingies, common on old machinery, that drip oil onto the works as part of a loss-based lubrication system.

Thought I had attached the image correctly...let's try again.

Looks like a grease zerk to me.

Could be grease or oil. Figure out what the manufacturer recommended. A lot of guys mistakenly pump grease in b/c 'it looks like a grease zerk'. They used them for oil too.

Regular zerk ****** - most grease guns will attach to it, you may have to remove it, soak it in acetone to soften the solidified grease, and reinstall.

Zerks were commonly used with 600W oil, which is a heavy oil originally used to lubricate steam-driven equipment/cylinders, and is now most commonly used to lubricate the heads of corn harvesters. Known in modern times as "Corn-Head Grease."

Is there a type/brand of oil or grease I should use? I don't want to get the wrong stuff gummed up in there if possible.

Unscrew see if it looks like old grease or dried oil and go from there

Without knowing the application ( what it's greasing / oiling ) it's difficult (if not impossible) to recommend any specific lube... What worked awesome for the 48" rocker pins on the bridge I worked on wouldn't work for your automotive bearings, and fail on anything that works in a wet environment...
