We need a replacement bearing for [equipment and position]. Attached are the full marking and packaging photos, drawing or maintenance reference, quantity and required date. The existing requirement is [complete manufacturer designation]; unreadable or unconfirmed fields are [items].

Please identify the exact version you propose and provide its specification and supply-record information. If it differs from the existing requirement, compare internal-clearance category, seals/shields, cage and lubrication or other special requirements as applicable. Explain the fit, speed, load, temperature and environmental assumptions used, and list any information still required.

Please separate a like-for-like offer from any alternative, identify deviations and the approval needed, and state what receipt documents and equipment-specific installation/trial checks should be agreed with the responsible technical authority. Do not treat an unanswered field as confirmed equivalence.
