Panoramica del prodotto

The 6701ZZ stands apart due to its exceptionally thin cross-sectional profile. This ultra-thin geometry makes it an extra-thin type bearing that is compact, lightweight, and suitable for thin-walled designs, enabling the miniaturization and weight reduction of your final product.

Caratteristiche principali:

Save space
The greatest advantage of 6701ZZ lies in its ultra-thin cross-sectional design. Its outer diameter is only 6 millimeters larger than the inner diameter, and its width is only 4 millimeters. This bearing can fit into spaces that standard bearings cannot accommodate. Whether you are developing ultra-thin medical devices, compact robotic joints, or portable consumer electronics, this bearing can provide the rolling support you need without affecting your industrial design goals. Its thin design also reduces the overall assembly weight – each 6701ZZ weighs only 3 to 5 grams, which is almost imperceptible in the overall system weight.
Liscio, Energy-Efficient Rotation
The 6701ZZ is engineered with precision ball-raceway contact geometry that minimizes rolling resistance. Low friction translates directly into two tangible benefits: reduced power consumption and extended component lifespan due to less heat generation and wear.
Hardness and Wear Resistance
The 6701ZZ’s rings and balls are manufactured from high-carbon chrome steel (GCr15), through-hardened to 58–62 HRC. This material provides excellent rolling contact fatigue resistance, maintaining raceway geometry under repeated stress cycles. The result is a long service life and consistent performance even in demanding, high-duty-cycle applications. For applications requiring corrosion resistance, stainless steel variants (S6701ZZ) are available on request.
High Rotational Accuracy
Precision manufacturing standards (ABEC?1 / P0 to ABEC?5 / P5 available) ensure that the 6701ZZ delivers consistent, vibration-free rotation. The balls are precisely matched to the raceway grooves, and the radial clearance is controlled within tight tolerances (typical C0 clearance ranges from 0.003mm to 0.018mm). For engineers developing positioning stages, optical instruments, or any application where motion quality affects outcome quality, this precision is non-negotiable. The low vibration characteristics also contribute to quieter equipment operation—a meaningful advantage in medical and office environments.
IL 6701Z.Z Thin Section Deep Groove Ball Bearing is engineered for applications where space, weight, and precision are critical. With its compact 12×18×4mm design, this ultra-thin bearing enables engineers to achieve high-performance motion control in space-constrained environments. It is an ideal choice for industries requiring miniaturization without compromising durability or efficiency.
