FAQS

QWhen should oil be used for bearings?

AIn conclusion, Kelly noted that in a properly designed closed system operating at moderate temperatures, the bearing oil should be replaced once per year. If operating temperatures exceed 80° C the oil may need to be replaced every three months.

QWhat is purpose of bearing lubrication?

APURPOSE OF LUBRICATION. Lubrication increases bearing life in most operating environments. The positive effects of lubrication may be summarized as follows: A lubricant film reduces friction and wear between the balls and raceways of the bearing, extending fatigue life.

QDo ball bearings need lubrication?

ASo most bearings use cages to separate and evenly space the balls. These cages cause friction and to reduce this friction, you generally need to lubricate your bearings, often with thick grease to ensure a long lifespan.

QWhat is a sealed ball bearing?

AThe sealed ball bearing is one which is completely sealed with lubricant inside. It prevents the flow of other lubricants into the rolling element area and also prevents the lubricant inside i.e. grease from getting out of the rolling element area.

QHow much grease is in a sealed bearing?

AUsing the chart and the formula, the bearing only needs 8 grams of grease every 10,000 hours. If your grease gun delivers around 1.35 grams per stroke, that means the bearing needs 6 strokes every 13 months; you could average it out to a stroke every 8 weeks or so.
