6220 Bearing Size (100x180x34 mm) & ZZ vs 2RS E Differences
The 6220 deep groove ball bearing features a 100 mm bore diameter, 180 mm outside diameter, and 34 mm width[1]. Designed as a heavy-duty single-row component within the 6200 series, it supports high radial loads and moderate axial forces in demanding industrial applications across Indonesia - from factory conveyor drives in Cikarang to heavy manufacturing machinery in Surabaya.
Selecting the correct 6220 bearing requires looking past the base part number to its enclosure suffix. HI-TEC SILVER supplies 6220 bearings in two primary variant options: 6220 2RS E featuring double rubber seals and 6220 ZZ featuring double metal shields. Matching the seal configuration to your machine's operating environment is vital to prevent premature failure, reduce machine downtime, and avoid expensive early replacements.
What are the exact dimensions of a 6220 bearing and its key variants?
The 6220 deep groove ball bearing features a 100 mm bore diameter, 180 mm outside diameter, and 34 mm width[1]. Standardized boundary dimensions ensure physical mounting compatibility across standard shafts and housings. HI-TEC SILVER supplies 6220 bearings in two variant options: 6220 2RS E featuring double rubber seals and 6220 ZZ featuring double metal shields.
| Specification / Feature | 6220 2RS E | 6220 ZZ |
|---|---|---|
| Bore Diameter (d) | 100 mm[1] | 100 mm[1] |
| Outside Diameter (D) | 180 mm[1] | 180 mm[1] |
| Width (B) | 34 mm[1] | 34 mm[1] |
| Series | 6200 Series | 6200 Series |
| Brand Tier | HI-TEC SILVER | HI-TEC SILVER |
| Enclosure Type | 2x Rubber Seal (Contact) | 2x Metal Shield (Non-contact) |
| Primary Protection | Dust, water spray, fine debris[2] | Coarse dust, direct debris[2] |
Both variants share identical outer physical dimensions, but their internal protection systems serve entirely different operating duties. The 6220 bearing from the HI-TEC SILVER line is engineered with high-quality materials to deliver a longer service life in industrial environments such as Jakarta workshops and Semarang processing plants.
What is the difference between 6220 2RS E and 6220 ZZ variants?
A shared 6220 series number does not guarantee part interchangeability because seal type selection depends strictly on environmental contamination and speed requirements. Ordering based solely on the 100 x 180 x 34 mm dimensions often leads to installing the wrong enclosure variant, causing elevated heat generation or contamination failure.
- 6220 2RS E (Double Rubber Seals): Utilizes contacting synthetic rubber lips that press against the inner ring[2]. This construction provides superior defense against fine dust, slurry, moisture, and wash-down conditions, making it ideal for agricultural equipment in Medan or mining units in Balikpapan. However, lip contact adds rotational friction, generating slightly higher heat at high speeds[2].
- 6220 ZZ (Double Metal Shields): Features non-contact steel plates fixed to the outer ring that leave a narrow gap near the inner ring[2]. It offers minimal friction, low running torque, and excellent performance at elevated speeds in clean industrial environments, such as enclosed electric motors or gearboxes in Bandung[2]. However, shields cannot block liquid ingress or airborne fine particulates[2].

Frequently Asked Questions
What are the exact dimensions of a 6220 bearing?
A 6220 deep groove ball bearing has a bore diameter of 100 mm, an outside diameter of 180 mm, and a width of 34 mm. These standard dimensions apply across open, metal-shielded (ZZ), and rubber-sealed (2RS E) variants.
What is the difference between 6220 2RS E and 6220 ZZ bearings?
The 6220 2RS E variant uses double contact rubber seals to block fine dust and moisture, creating higher friction. The 6220 ZZ variant uses double non-contact metal shields designed for lower friction and higher speeds in cleaner operating environments.
Are all 6220 series bearings interchangeable?
No, 6220 bearings are not universally interchangeable. While their 100 x 180 x 34 mm boundary dimensions match, substituting a metal-shielded ZZ bearing into a high-moisture or dirty environment where a sealed 2RS E is required will lead to premature failure.
How can I check price and availability for HI-TEC SILVER 6220 bearings?
