Material & Construction
The material is stated as Bearing Steel (GCr15). That choice of wear material sets the service life of the working surfaces and, together with the casting weight, most of the unit price. It is the figure buyers confirm against a wear-life figure or a reference installation before ordering.
Capacity & Drive
Rated performance is given as limit speed(grease)(r/min) rated at 950. Nameplate capacity assumes a defined feed size and bulk density. Ask for the curve rather than the single number if the plant has to hold a product-size specification.
Dimensions & Packing
Dimensions and shipping data are stated as width(mm) of 73 and packing as 1. Neutral Packing Bearing 2. Industrial Packing 3. Commercial Packing Bearing 4. Customize. For heavy units the packing format is part of the quote: skid, crate or container loading changes both the freight cost and the unloading equipment required on site.
Customisation & OEM Service
OEM production covers the nameplate, the paint scheme and the electrical configuration, plus frame modifications within the limits of the existing pattern. A drawing review normally comes back with the quotation. For this item, minimum order quantity is 1 Piece and the reference price starts at US$1.00-50.00 per set.
Ordering & Samples
Ordering starts with the duty specification and a layout drawing, followed by a proforma against the confirmed configuration. Delivery schedules are quoted per order rather than published on the page.
