Seal Design Notes

Seal construction
Metal shields on both sides. No rubber sealing-ring material is specified.
What it shields
The shields help limit dust entry and grease escape on both sides. They should not be treated as a specified water barrier.
Effect on speed
The listed grease-lubricated limiting speed is 100% of the open version for the same base model. Select against the actual speed in the specification table.
Lubrication
The factory table specifies grease lubrication and provides no oil-lubricated limiting speed. Confirm suitability with GDQV before specifying an oil-lubricated arrangement.
When to choose it
Consider ZZ for a grease-lubricated assembly needing shields on both sides. Confirm grease life and maintenance requirements for the operating conditions.
