6013-2Z Deep Groove Ball Bearing For Industrial Electric Motors & Heavy-Duty Pumps | 65×100×18 mm

6013-2Z Deep Groove Ball Bearing For Industrial Electric Motors & Heavy-Duty Pumps | 65×100×18 mm

The 6013-2Z is a medium-sized deep groove ball bearing engineered for demanding industrial applications requiring robust load capacity and reliable long-term operation. Featuring double metal shields (2Z), this configuration provides effective protection against coarse particulate contamination while maintaining low frictional torque for energy-efficient performance. With a 65mm bore, 100mm outer diameter, and 18mm width, it is widely adopted as a critical component in industrial electric motors, centrifugal pumps, gearboxes, and ventilation systems where consistent performance under sustained radial and axial loads is essential.

6013-2Z Deep Groove Ball Bearing 65x100x18 mm | Metric Series | Double Shielded

Manufactured to strict ISO dimensional standards, the 6013-2Z features classic deep groove geometry optimized for high radial load capacity and moderate bidirectional axial thrust. The pressed steel shields effectively retain lubricating grease while preventing ingress of larger debris, making this bearing suitable for continuous operation in industrial environments. Its standardized dimensions ensure direct interchangeability with major bearing manufacturers.

Key Performance Features

01. High Load Capacity for Demanding Applications

The 6013-2Z utilizes a full complement of precision-ground balls within deep raceway grooves, delivering substantial dynamic and static load ratings. This robust internal geometry enables the bearing to withstand significant radial forces while accommodating moderate axial loads in either direction. The design ensures reliable performance in applications subject to shock loads or continuous heavy-duty operation.

02. Shielded Configuration for Industrial Environments

The 2Z suffix indicates double non-contact metal shields constructed from pressed steel. These shields create a narrow labyrinth gap that protects the internal components from coarse dust and debris without introducing significant frictional drag. This configuration balances protection with speed capability, making it ideal for industrial equipment operating in moderately contaminated conditions.

03. Durable Construction for Extended Service Life

Constructed from vacuum-degassed high-carbon chromium steel (GCr15 / SAE 52100), the 6013-2Z undergoes precision heat treatment to achieve optimal hardness and wear resistance. The pressed steel cage provides reliable guidance of the rolling elements under variable load conditions, while the precision-honed raceways ensure smooth rotation and minimal vibration throughout the bearing's service life.
