SNR 6306 ZZ HT200 30x72x19 - Industrial Sealed Ball Bearing

Main Description

The SNR 6306 ZZ HT200 bearing, with dimensions 30 mm (inner diameter) x 72 mm (outer diameter) x 19 mm (width), is a heavy-duty, sealed industrial ball bearing designed for demanding mechanical and industrial applications. Its robust construction ensures long service life, low friction, and reliable rotational performance, even under continuous load and in environments exposed to dust, contaminants or lubrication.

This sealed bearing (ZZ) features metal shields on both sides, protecting internal components from dust, dirt, and moisture — making it an excellent choice for applications where reliability and minimal maintenance are priorities. The bearing’s internal design ensures smooth, stable rotation of shafts, axles, or rollers, while the outer dimensions conform to widely used industry standards, enabling easy retrofitting or replacement.

In industrial settings — including gearboxes, electric motors, conveyor systems, pumps, fans, and general machinery — the SNR 6306 ZZ HT200 stands out as a versatile bearing unit suitable for both new installations and maintenance operations. It delivers consistent performance for tasks requiring moderate to heavy loads, moderate speed, and dependable sealing.

As part of an integrated bearing housing or mechanical assembly, the SNR 6306 ZZ HT200 supports operational stability and reduces downtime risk. For procurement managers, maintenance teams or OEM suppliers, the bearing offers a cost-effective, durable solution — combining strength, sealing, and compatibility.

Technical Data

FAQ

Q1: What does “6306 ZZ HT200” mean?
A1: The “6306” denotes the bearing size (30 mm ID, 72 mm OD, 19 mm width). “ZZ” indicates metal shields on both sides, providing sealing. “HT200” is the manufacturer’s designation, often signifying a specific production series or material/quality grade by SNR.

Q2: Is this bearing suitable for industrial machinery and heavy-duty use?
A2: Yes — the SNR 6306 ZZ HT200 is designed for industrial applications including motors, gearboxes, pumps, and other rotating equipment, offering durability, stability, and low maintenance thanks to its sealed design.

Q3: Can I use this bearing in a bearing housing or bearing unit?
A3: Absolutely — the standard 30x72x19 mm dimensions and sealed construction make it easy to integrate into bearing housings or bearing units in mechanical assemblies, gearboxes or conveyor systems.

Q4: Does the sealed design eliminate the need for maintenance?
A4: While sealing significantly reduces contamination risk and extends service intervals, periodic inspection is still recommended under heavy load, high dust or high humidity conditions. Regular monitoring ensures maximum bearing lifespan.

Q5: When is this bearing particularly recommended?
A5: It is especially useful in applications exposed to dust, contaminants or where maintenance access is limited — e.g. industrial motors, fans, pumps, conveyors, compressors, and general machinery requiring sealed bearings.
