To relubricate Y-bearing units, the following greases can be used:
Y-bearing units comprising either zinc-coated and stainless steel bearings
→ food-grade grease SKF LGFP 2
all other Y-bearing units
→ SKF LGWA 2, LGMT 2 or LGMT 3 grease
Relubrication features for housings made of:
Grease fitting with a 1/4-28 SAE-LT thread.
- The hole for the grease fitting has a 1/4-28 UNF thread, which can be changed to G 1/4, using an LAPN 1/4 UNF adapter.
- Grease fitting with a 1/4-28 SAE-LT thread.
Composite for SKF Food Line
- Relubrication feature available on request (designation suffixes N and VZ1A2 combined).
SKF Y-bearings are designed to facilitate relubrication. They have two lubrication holes in the outer ring as standard, one on each side, positioned 120° apart.
Bearings without lubrication holes can be supplied on request (designation suffix W).The following bearings do not have the standard relubrication features:
Stainless steel Y-bearings with grub screws have a lubrication groove in the outer ring located on the side opposite the locking device and one lubrication hole within this groove. Stainless steel bearings with designation suffix GR have these features located at the side of the locking device.
- Y-bearings with a standard inner ring without designation suffix B and Y-bearings with 5-lip seals are lubricated for life and cannot be relubricated. They do not have any lubrication holes.
