Decoding the designation

K — Needle roller and cage assembly. The cage holds the rollers; there are no inner or outer rings, so the shaft and the housing bore form the raceways.

35X42X18 — The three governing dimensions in millimetres: roller complement inner diameter, roller complement outer diameter and width.

What these specs mean in practice

Dynamic Load Rating: 27,500 N. Static Load Rating: 43,000 N. Limiting Speed: 12,700 rpm. Reference Speed: 7,100 rpm. Fatigue load limit, radial: 6,100 N. Lubricant: grease or oil. Operating temperature range: -30 °C to +140 °C.

A cage assembly gives the highest load rating per unit of radial space of any rolling bearing arrangement, because the 3.5 mm wall between 35 mm and 42 mm contains nothing but rollers. That is why 27,500 N dynamic fits in a 42 mm bore. Static above dynamic is normal for the type.

Series: K. Base Number: K35X42X18.
