INGCO S-RH-NB1210-RH15008 Rotary Hammer Drill-NEEDLE BEARING HK1210

The HK1210 is a needle roller bearing commonly used in rotary hammer drills. It’s a small, cylindrical bearing with many tiny needles for rolling elements. These needles minimize friction between rotating parts within the drill.

Components:

• Inner race: The inner ring that fits onto a rotating shaft.
• Outer race: The stationary housing for the needles and inner race.
• Needle rollers: Thin, cylindrical rollers that provide low-friction rolling contact.
• Cage:  Holds the needles in place and keeps them evenly spaced.

Uses:

. In a rotary hammer drill, it typically supports the shank, the part that connects the drill bit.

The HK1210 bearing is ideal for applications that experience high radial loads (force pushing inwards) with limited space available .In a rotary hammer drill, it typically supports the shank, the part that connects the drill bit. In a rotary hammer drill, this bearing plays a critical role by supporting the shank, ensuring its smooth rotation during drilling operations.

How it Works:

The HK1210 allows the shank to rotate smoothly within the hammer drill housing. This rotation is independent of the hammering action, which is achieved by a separate mechanism. The needles distribute the load from the shank rotation, reducing friction and wear.

The HK1210 bearing facilitates the smooth rotation of the drill’s shank, the part that connects and spins the drill bit. This rotation happens independently of the hammering action, which is a separate mechanism within the drill. The numerous needle rollers distribute the load caused by the shank’s rotation, significantly reducing friction and wear between moving parts.

Applications:

• • Rotary hammer drills
  • Demolition hammers
  • Chipping hammers
  • Other power tools with rotating shafts under high radial loads
