R188 ZZ 1/4″ x 1/2″ x 3/16″ Chrome Steel Miniature Deep Groove Ball Bearing

제품개요

The R188ZZ miniature deep groove ball bearing is engineered to deliver precision performance in a compact inch-size package. With exacting dimensions of 1/4″ bore, 1/2″ outer diameter, and 3/16″ width (6.35 mm × 12.7 mm × 4.762 mm), this bearing is the preferred choice for applications where space is limited but smooth, low-friction rotation is critical.

주요 특징:

• Ultra-Compact Inch-Size Footprint
  With a 1/4″ bore and just 3/16″ width, the R188ZZ fits into the tightest mechanical assemblies. Its miniature dimensions enable the miniaturization of skateboard wheels, 요요, RC 모델, and precision instruments without sacrificing performance.

• 고속
  최대 40,000 RPM – The R188ZZ is engineered for high-speed operation, with a grease-lubricated limiting speed of 40,000 RPM. This speed capability makes it ideal for yo-yos, RC motors, and other applications where rotational velocity is critical to performance.

• 낮은 마찰, 저소음, 원활한 작동
  궤도와 볼의 정밀 연삭으로 마찰 계수가 매우 낮습니다., reducing power consumption, heat generation, and audible noise. The R188ZZ delivers quiet, smooth rotation that enhances user experience in yo-yos, 스케이트보드, 정밀 기기.
• 다목적 부하 처리
  Radial and Moderate Axial Loads – As a deep groove ball bearing, the R188ZZ is designed to handle radial loads as its primary duty while also accommodating moderate axial (추력) 양방향으로 하중을 가함. This versatility reduces the number of bearings required in an assembly and simplifies mechanical design.
• 경량 디자인
  Weighing just 2.24 그램, the R188ZZ adds minimal mass to moving assemblies, reducing inertia and enabling faster acceleration and deceleration.
