Which device is commonly used to deliver lubricant to the bearing surfaces in sleeve-type bearings?

• A. Slinger Ring
• B. Gland Packing
• C. Wick
• D. O-Ring

Answer: (A)

The lubricating film for sleeve-type bearings is typically created by a slinger ring. This ring is mounted on the shaft near the bearing and spins with it. As the shaft rotates, the ring throws oil outward by centrifugal force, splashing lubricant onto the bearing surfaces to form a film. This provides continuous lubrication around the bearing circumference and helps prevent overheating and wear without relying on external pumps. Gland packing and O-rings are seals, not oil-delivery devices, while a wick uses capillary action but is less effective for reliably supplying a full bearing surface in most sleeve bearings.
