6316 ZZ Deep Groove Ball Bearing 80x170x39 mm | 6300 Series | Double Shielded Design
A cornerstone of industrial power transmission, this bearing utilizes the proven deep groove geometry to ensure high radial load capacity and low friction. Engineered for consistent operation at speeds reaching 4,500 r/min with grease lubrication. The 6316 ZZ is manufactured to handle the demanding conditions of continuous operation, making it a trusted component for heavy mechanical drives and industrial equipment.

This versatile bearing is ideally suited for a wide array of general and heavy industrial machinery:
Manufactured to standard industrial precision (P0) with an option for higher grades (P5), the 6316 ZZ ensures consistent quality. The precision-machined deep raceway grooves and the high conformity of the balls facilitate stable, vibration-free rotation, contributing to efficient power transmission and reduced noise levels in machinery.
As a member of the 63-series heavy-duty family, the 6316 ZZ offers a significantly higher radial load rating compared to smaller series. Manufactured from high-purity chrome steel (GCr15/SAE 52100), its design ensures superior durability and resistance to wear, guaranteeing an extended service life under continuous, demanding loads.
This variant comes standard with double metal shields (ZZ) , providing excellent protection against the ingress of large debris and dust while retaining lubricating grease for low-maintenance operation . As a fundamental industrial size, the 6316 platform is also available in open, sealed (2RS), or with increased clearance (C3) variants to suit specific environmental and thermal operating conditions.

While the 6316 ZZ is supplied as standard with double shields for grease retention and debris protection, the base open design allows for customization to meet specific operational demands:
• Double Shield (6316-ZZ / 2Z): Standard configuration. Provides a good balance of protection and low torque for general industrial use.
• Double Seal (6316-2RS / 2RS1): For enhanced protection against moisture, dust, and fine contaminants in harsh environments.
• Open Bearing (6316): For high-speed applications requiring oil lubrication or custom grease packing.
• Increased Clearance (6316 ZZ C3): Suitable for applications where interference fits or temperature differentials might otherwise reduce internal clearances.
"For heavy electric motors, industrial gearboxes, and aggregate processing equipment, the 6316 ZZ offers a robust and reliable bearing solution. Specify seal suffixes (2RS) or C3 clearance to perfectly match your operating environment."
