Refilling lubricant
The grease travels through the circulating grooves and bores via lubrication nipples into
the interior of the bearing. The greasing quantity is 2 oz. (60g) to 3.5 oz. (100g) roller
bearing grease F3 per bearing.
Replacing lubricant
Renewing the lubricant between the specified intervals is only necessary when unusual
bearing noises or overheating occurs. Mounting and dismounting the bearings must be
performed according to the instruction in the operation manual.
Follow the steps below to replace the lubricant.
1. Open the bearing.
2. Remove the bearing housing and the bearing cover.
3. Carefully clean the bearing with petroleum ether. (Petroleum ether, petroleum,
spirit, aqueous neutral, or alkaline cleaning agents may be used to clean the
bearings.) The bearing must be immediately preserved with the lubricant after
cleaning in order to avoid corrosion.
4. Fill the bearing with an approved lubricant (see “list of lubricants”).
